Why does Jupiter take 12 years to orbit the Sun?
When it comes to the other planets that make up our Solar System, some pretty stark differences become apparent. In addition to being different in terms of their sizes, composition and atmospheres from Earth, they also differ considerably in terms of their orbits.
- Whereas those closest to the Sun have rapid transits, and therefore comparatively short years, those farther away can take many Earth to complete a single orbit.
- This is certainly the case when it comes to Jupiter, the Solar System largest and most massive planet.
- Given its considerable distance from the Sun, Jupiter spends the equivalent of almost twelve Earth years completing a single circuit of our Sun.
Orbiting at this distance is part of what allows Jupiter to maintain its gaseous nature, and led to its formation and peculiar composition.
Is Jupiter’s orbit unusual?
Our Solar System Would Be Weird Even If It Didn’t Harbor Life W hat would our solar system look like if an alien were to spot it from another planet, orbiting a distant star? How improbable would it appear? For the first time in human history, thanks to advances in exoplanet hunting, we can now answer that question. Sean Raymond Pretty sparse, isn’t it? No Earth or Mars. No rocky planets at all! No Saturn, no asteroid belt, no ice giants. All the aliens would detect is Jupiter. This is because the other solar system planets and objects are all either too far away from the sun, too small to detect, or both.
The alien could pinpoint Jupiter’s mass and orbit with decent precision, because our star, the sun, would show a telltale wobble—the force of Jupiter’s gravity tugging on it as it orbits—but that’s all. It would just see a sun-Jupiter system. But how common are sun-Jupiter systems in our galactic neighborhood? Such a system, as the term suggests, has at least one planet that’s so massive that the center of gravity between it and the star it orbits lies outside that star (the center of gravity between each of the other planets and the sun, in our solar system, lies within the sun’s radius).
Is our sun-Jupiter pair anything like the norm? Let’s start with the sun. It turns out that our home star is a little bit unusual, but not a lot. This image shows a census of all the stars within 30 light-years of the sun: Neighborhood stars: Distribution of the types of stars within 30 light-years of the Sun (21 white dwarfs are not included on the plot). Franck Selsis, with data from solstation.com Our sun is a G star—normally white to yellow in color with a surface temperature around 5,000 to 6,000 Kelvin.
There are 20 G stars within 30 light-years out of almost 400 total stars. The majority of stars are M stars, also known as “red dwarfs”. These small red stars have much longer lifetimes than G stars but shine much fainter. Among nearby stars, the sun is modestly weird. If you give our definition of a “sun-like” star some latitude, our star ends up being rare—10 percent of the nearby stars are like it, about the fraction of American adults who are vegetarian.
Now let’s turn our attention to Jupiter. First, take a look at our current census of extra-solar planets. Here is a plot of the almost 3,000 planets that have been discovered in the past two decades; the x-axis represents the planets’ distance from their home stars, the y-axis their mass: Nautilus Members enjoy an ad-free experience. Star Chart: The distribution of extra-solar planets in terms of their masses (y axis) and the size of their orbits (x axis). Colors correspond to the detection technique. The solar system planets are included. Data from exoplanets.org. Sean Raymond Like the sun, Jupiters are just a little out of the ordinary.
- As are our rocky planets: None of the known extra-solar planets line up with them, or with Saturn, Uranus, or Neptune.
- But we already knew this; it’s why we are searching for sun-Jupiter systems and not complete solar systems.) Only 10-15 percent of sun-like stars have a gas giant planet like Jupiter, with a mass larger than 50 Earths.
Another factor that makes our Jupiter more unusual is its orbit: It’s nearly circular (an ellipse with an eccentricity of just 5 percent) and it’s more than five times larger than Earth’s orbit. Among the other known gas giants, on the other hand, only about 10 percent have orbits wider than Mars’ (which is only 1.5 times larger than Earth’s) that are nearly circular (with eccentricities less than 10 percent).
Putting those together, only about 1 percent of stars like the sun has a Jupiter like ours—a little less likely than being dealt 3-of-a-kind in a 5-card poker hand. There is one more aspect of the solar system that is unusual. It’s not something about the planets that we have; it’s something that is missing.
About half of all stars like the sun are orbited by at least one “hot super-Earth” planet. These planets are generally Earth-sized or larger, with orbits around the sun smaller than Mercury’s. We don’t know why the solar system is deficient in super-Earths, although one idea suggests that,
How exactly does the structure of a planetary system affect its ability to host life, if at all? Let’s put the pieces together to calculate how unusual our solar system is: The fraction of stars that are like the sun (10 percent), multiplied by the fraction of sun-like stars with Jupiters (10 percent), multiplied by the fraction of Jupiter-like planets with Jupiter-like orbits (10 percent), multiplied by the fraction of sun-like stars with no hot super-Earths (50 percent), gets us 0.05 percent.
This tells us that about one in every 2000 stars in our galactic neighborhood is a sun-Jupiter system. Those are about the odds of being picked if you apply to NASA to be an astronaut. But what does this mean? It means the solar system is not a dime-a-dozen kind of planetary system even without considering that it harbors life.
- Most systems are different than ours.
- Most planetary systems orbit puny red dwarfs instead of big yellow G stars like the sun.
- Most systems contain super-Earths close to their stars, and if they happen to have a gas giant, it tends to be much closer to its sun, or have a much more stretched-out orbit than Jupiter’s.
But we don’t know how many sun-Jupiter systems also have Venuses, Earths, Saturns or Marses. And we don’t know how common Earths and Saturns are in systems without Jupiters or systems that orbit red dwarfs. We really want to know whether there is a reason for life-bearing planets to prefer sun-Jupiter systems, like ours.
How exactly does the structure of a planetary system affect its ability to host life, if at all? Nautilus Members enjoy an ad-free experience. or, We are still looking for the answers to those questions. The Juno spacecraft, now in orbit around Jupiter, will likely shed some light on them. “Some of the answers undoubtedly lie in the general physics of gravitational systems, and in the intrinsic attraction of gases and particles that swirl around a baby star as it gathers itself up out of the chill soup of interstellar material,” writes astrobiologist in his 2014 book The Copernicus Complex,

Why is Jupiter year longer than Earth?
Jupiter Jupiter – Rotating Model Credit: and the largest planet in the, It is more than twice as massive as all the other planets in our Solar System put together. It is so big that all the other planets would fit inside it! As huge as Jupiter is, it is only a thousandth the of the Sun.
And 11,000 planet Jupiter’s could fit inside ! Jupiter is a gas giant, This means that is does not have a solid surface. It is mostly made of gas and is thought to have a small solid core. Jupiter is made up of mainly hydrogen (75%) and helium (24%). The light coloured bands of cloud are made of ammonia ice and are called zones.
The darker coloured bands, or belts, are thought to be made up of sulphur, and phosphorus. Jupiter spins faster than any other planet in the Solar System. One day on Jupiter is around 10 hours long! Even though it’s day is much shorter than the Earth’s its year is longer.
- This is because Jupiter is much further from the Sun.
- It takes 12 years for Jupiter to go around the Sun once.
- One of the most famous features of Jupiter is the Great Red Spot.
- This is a giant storm, which has been raging for at least 150 years.
- The storm is twice the size of the Earth.
- Jupiter has dozens of.
The largest four were discovered in 1610 by Galileo. They are called:,, and, We don’t think that life could survive on Jupiter. But when scientists look for places life could live in the Solar System they often look at Europa. The oceans on Europa, under the icy crust, might be one of the best places for life to evolve.

Does Jupiter have a core?
According to most theories, Jupiter has a dense core of heavy elements that formed during the early solar system. The solid core of ice, rock, and metal grew from a nearby collection of debris, icy material, and other small objects such as the many comets and asteroids that were zipping around four billion years ago.
- These bits of matter clumped together due to their mutual gravity, becoming larger chunks called planetesimals, which, in turn, collided and stuck together to form Jupiter’s core.
- Soon, the core grew big enough so that it had enough gravity to attract even hydrogen and helium, the lightest elements that exist.
More and more gas accumulated until it became what we now know as Jupiter. Although most scientists agree on this general story, many details remain unknown. For example, we’re still not sure where all the icy matter comes from. Another theory, however, suggests that there’s no core at all.
- Instead, Jupiter formed from the large cloud of gas and dust that surrounded the Sun soon after its birth.
- As this cloud cooled and condensed, gas and dust particles lumped together so that some regions were denser than others.
- One of these dense splotches was able to gravitationally pull more and more gas and dust together, swelling into a full-fledged planet.
By measuring Jupiter’s gravitational and magnetic fields, Juno will be able to determine whether a core exists. If it does, exactly what the fields look like will depend on how big it is. Different theories make different predictions about the core, and knowing the size will help determine which theory – if any – is more likely to be correct.
Could Jupiter become a star?
Could Jupiter become a star? Asked by: Louise Dryden, Cardiff Jupiter is often called a ‘failed star’ because, although it is mostly hydrogen like most normal stars, it is not massive enough to commence thermonuclear reactions in its core and thus become a ‘real star’.
But the term ‘failed star’ is a bit of a misnomer. Theoretically, any object at all could be made into a star, simply by adding enough matter to it. With enough mass, the internal pressure and temperature of the object will reach the threshold needed to start thermonuclear reactions. That threshold is the least for the simplest element, hydrogen.
In order to turn Jupiter into a star like the Sun, for example, you would have to add about 1,000 times the mass of Jupiter. But, to make a cooler ‘red dwarf’ you would only need to add about 80 Jupiter masses. Although the exact numbers are still a bit uncertain, it is possible that a ‘brown dwarf’ could still form (in which deuterium, rather than hydrogen, fuses in the star’s core) with only about 13 Jupiter masses.
Would you age quicker on Jupiter?

Can Earth fit in Jupiter’s storm?
Hubble Shows that Jupiter’s Great Red Spot Is Smaller than Ever Seen Before Jupiter’s monster storm, the Great Red Spot, was once so large that three Earths would fit inside it. But new measurements by NASA’s Hubble Space Telescope reveal that the largest storm in our solar system has downsized significantly. The red spot, which has been raging for at least a hundred years, is only the width of one Earth.
What is happening? One possibility is that some unknown activity in the planet’s atmosphere may be draining energy and weakening the storm, causing it to shrink. The Hubble images were taken in 1995, 2009, and 2014. Jupiter’s trademark Great Red Spot – a swirling anticyclonic storm feature larger than Earth – has shrunken to the smallest size ever measured.
Astronomers have followed this downsizing since the 1930s. “Recent Hubble Space Telescope observations confirm that the Great Red Spot (GRS) is now approximately 10,250 miles across, the smallest diameter we’ve ever measured,” said Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Md.
Historic observations as far back as the late 1800s gauged the GRS to be as big as 25,500 miles on its long axis. The NASA Voyager 1 and Voyager 2 flybys of Jupiter in 1979 measured the GRS to be 14,500 miles across. Starting in 2012, amateur observations revealed a noticeable increase in the spot’s shrinkage rate.
The GRS’s “waistline” is getting smaller by 580 miles per year. The shape of the GRS has changed from an oval to a circle. The cause behind the shrinking has yet to be explained. “In our new observations it is apparent that very small eddies are feeding into the storm,” said Simon.
“We hypothesized that these may be responsible for the accelerated change by altering the internal dynamics and energy of the Great Red Spot.” Simon’s team plans to study the motions of the small eddies and also the internal dynamics of the GRS to determine if these eddies can feed or sap momentum entering the upwelling vortex.
In the comparison images one Hubble photo was taken in 1995 when the long axis of the GRS was estimated to be 13,020 miles across. In a 2009 photo, the GRS was measured at 11,130 miles across. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency.
Can you land on Jupiter?
Surface – As a gas giant, Jupiter doesn’t have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn’t be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet crush, melt, and vaporize spacecraft trying to fly into the planet. Atmosphere
How hot is Jupiter?
According to NASA, the mean temperature of Jupiter is -166 °F. The average temperature of Jupiter’s surface is about -238 °F. Since the planet is a gas giant, temperatures vary throughout the layers of clouds that give the planet the appearance known to people.
Would we age slower on Jupiter?
On Jupiter you would age only slightly more slowly than on the earth. It doesn’t have nearly enough gravty to make a noticeable change.
What is the largest known planet?
What’s the biggest planet in the Solar System? – Illustration of Jupiter © Getty The biggest planet in the Solar System is Jupiter. It’s a bit of a brute. The gas giant weighs over double that of every other planet in the Solar System combined, Thanks to its gargantuan size and large gravitational pull ensure that it holds 80 confirmed moons in orbit.
To put it in increased perspective, the fifth planet from the Sun has a radius of 69,911km, making it approximately 11 times wider than the Earth’s 6,371km. If Earth were the size of a 20p coin, Jupiter would be about as big as a football. In terms of surface area, Jupiter measures 61,418,738,571km², compared to Earth’s 510,064,472km².
The Sun, however, is much larger still. While Jupiter’s diameter is around 11 times larger than the Earth’s, it is around ten times smaller than the Sun’s. Yet while Jupiter is for sure the largest known planet in the Solar System, there are bigger ones out there.
What is the hottest planet?
Kid-Friendly Venus – Venus is the second planet from the Sun and Earth’s closest planetary neighbor. Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid.
- The atmosphere traps heat, making it feel like a furnace on the surface.
- It’s so hot on Venus, the metal lead would melt.
- Venus is sometimes called Earth’s twin because it’s similar in size and structure, but the planets are very different in other ways.
- In addition to being extremely hot, Venus is unusual because it spins in the opposite direction of Earth and most other planets.
It also has a very slow rotation making its day longer than its year. Visit NASA Space Place for more kid-friendly facts. NASA Space Place: All About Venus ›
Is Jupiter 100% gas?
Structure and Composition: – Jupiter is composed primarily of gaseous and liquid matter, with denser matter beneath. It’s upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium by percent volume of gas molecules, and approx.75% hydrogen and 24% helium by mass, with the remaining one percent consisting of other elements. Jupiter’s structure and composition. Credit: Kelvinsong CC by S.A.3.0 The atmosphere contains trace amounts of methane, water vapor, ammonia, and silicon-based compounds, as well as trace amounts of benzene and other hydrocarbons. There are also traces of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphine, and sulfur.
- Crystals of frozen ammonia have also been observed in the outermost layer of the atmosphere.
- The interior contains denser materials, such that the distribution is roughly 71% hydrogen, 24% helium and 5% other elements by mass.
- It is believed that Jupiter’s core is a dense mix of elements – a surrounding layer of liquid metallic hydrogen with some helium, and an outer layer predominantly of molecular hydrogen.
The core has also been described as rocky, but this remains unknown as well. In 1997, the existence of the core was suggested by gravitational measurements, indicating a mass of 12 to 45 times the mass of Earth, or roughly 4%–14% of the total mass of Jupiter.
- The presence of a core is also supported by models of planetary formation that indicate how a rocky or icy core would have been necessary at some point in the planet’s history.
- Otherwise, it would not have been able to collect all of its hydrogen and helium from the protosolar nebula – at least in theory.
However, it is possible that this core has since shrunk due to convection currents of hot, liquid, metallic hydrogen mixing with the molten core. This core may even be absent now, but a detailed analysis is needed before this can be confirmed. The Juno mission, which launched in August 2011 (see below), is expected to provide some insight into these questions, and thereby make progress on the problem of the core.
Is Jupiter’s core hot or cold?
What’s It Like Inside Jupiter? | NASA Space Place – NASA Science for Kids It’s really hot inside Jupiter! No one knows exactly how hot, but scientists think it could be about 43,000°F (24,000°C) near Jupiter’s center, or core, The reddish brown and white stripes of Jupiter are made up of swirling clouds. The well-known Red Spot is a huge, long-lasting storm. Image credit: NASA/JPL/Space Science Institute is made up almost entirely of hydrogen and helium. On the surface of Jupiter–and on Earth–those elements are gases.
Is any part of Jupiter solid?
Ask an Astronomer We do not yet know if a solid surface exists on Jupiter. Jupiter’s clouds are thought to be about 30 miles (50 km) thick. Below this there is a 13,000 mile (21,000 km) thick layer of hydrogen and helium which changes from gas to liquid as the depth and pressure increase.
Beneath the liquid hydrogen layer is a 25,000 mile (40,000 km) deep sea of liquid metallic hydrogen. Beneath this, there might be a solid core which is about one and a half times the size of Earth, but thirty times more massive. The temperature here would be about 55,000 Fahrenheit (30,000 Celsius) and the pressure would be tremendous because of the weight of the atmosphere above.
So, if it is a solid surface, it’s not at all like what you would find on a rocky planet, and it’s not something you could walk on.
Is Saturn losing its rings?
Home News Science & Astronomy
An artist’s impression of how Saturn may look in the next hundred million years. The innermost rings disappear as they rain onto the planet first, very slowly followed by the outer rings. (Image credit: NASA/Cassini/James O’Donoghue) Saturn’s rings are disappearing, and we don’t know how much longer they will be around.
- Astronomers have known since the 1980s that Saturn ‘s icy innermost rings are steadily eroding onto its upper atmosphere.
- The downpour is happening at such a high rate that an Olympic-sized swimming pool of water rains on the gas giant daily.
- However, how quickly the iconic ring system is shrinking — which determines when it will vanish — continues to be an open question.
Luckily, NASA’s mighty James Webb Space Telescope (JWST or Webb), whose powerful instruments have so far peered at faraway galaxies from the early universe, will soon investigate this intriguing phenomenon found much closer to home. “We’re still trying to figure out exactly how fast they are eroding,” James O’Donoghue, a planetary scientist at the Japan Aerospace Exploration Agency who will lead the new effort to pin down how long Saturn’s rings will last, said in a statement published Monday (April 17).
“Currently, research suggests the rings will only be part of Saturn for another few hundred million years.” Related: Saturn: Everything you need to know about the sixth planet from the sun To better estimate the lifetime of Saturn’s iconic rings, JWST and the Keck Observatory in Hawaii will be part of a long-term observation campaign to study the planet.
The telescopes will help monitor how the “ring rain” phenomenon fluctuates during one full season on the gas giant, which lasts about seven Earth-years thanks to its orbit far away from the sun, Astronomers expect interesting data from the campaign, as previous research showed that huge amounts of ring material is constantly dropping onto Saturn.
For example, data sent home from NASA’s Cassini spacecraft — which cruised right through the gap between Saturn and its rings 22 times during its death dive into the planet in 2017 — had revealed that somewhere between 880 pounds (400 kg) and 6,000 pounds (2,800 kg) of icy rain is flowing onto the planet every second and heating its upper atmosphere,
At this rate, the rings might vanish in about 300 million years. Although that may seem like a long time away, the deluge is leading the symbolic ring system to ” a relatively quick death ” in cosmic timescales. But the rate at which the ring material is raining onto the planet is still largely uncertain; the rings could disappear as quickly as 100 million years, or they might hang around for 1.1 billion years, astronomers say.
- Right now we only have one very wide estimate,” O’Donoghue told Space.com on Wednesday (April 26).
- We want to make more observations which narrow down this influx range.” According to the current research, space rocks and the sun’s radiation slightly disturb the ring particles and give them an electrical charge such that they bind to the gas giant’s magnetic field lines.
Saturn’s gravity then pulls the icy particles in, which are guided by the magnetic fields to flow into the planet’s upper atmosphere, but not always at the same pace. Details of Saturn’s icy rings are visible in this sweeping view from Cassini of the planet’s glorious ring system. The total span, from A ring to F ring, covers approximately 40,800 miles (65,700 km) and was photographed at Nov.26, 2008. (Image credit: NASA/JPL/Space Science Institute) As Saturn goes around the sun in its 29.5-year orbit, it shifts toward and away from the sun, and its rings do the same.
- This tilt dictates how much the sun’s radiation affects the ring system’s innermost layers — where much of the icy rain is being triggered — and may also play a role in determining how much material is dropping onto Saturn, astronomers say.
- We suspect that when the rings are edge-on with the sun, the ring rain will slow down,” O’Donoghue told Space.com.
“And that when they are tilted to face the sun, the ring rain influx will increase.” So his team will use the Webb and the Hawaiian Keck observatories to measure emissions sprouting from a specific hydrogen molecule in Saturn’s upper atmosphere. Measurements of this molecule spike when a small amount of material from Saturn’s icy rings tumbles down into its atmosphere, but it dwindles during abundant ring rain, O’Donoghue told Space.com.
- Monitoring these shifts in these hydrogen emissions throughout one complete season on Saturn could help the team nail down just how much ring material must be raining on the planet.
- The instrument on Keck we have used for this before has been upgraded, and we’ve never used JWST for this before,” he said.
“So we’ll be able to estimate the ring influx better than ever before.” While the new research will help with forecasting the fate of the rings, astronomers studying the Saturnian world continue the decades-old debate about how and when the planet’s rings were born in the first place.
- Various models had shown that the rings had been a permanent structure around Saturn since 4.5 billion years ago — when the solar system itself was forming, but data from the Cassini spacecraft painted a more youthful picture, aging them at just 10 million to 100 million years old.
- The discrepancy arose because older rings are often darker, but Cassini had captured Saturn’s rings to be bright, hinting at their youth.
In 2019, astronomers who revisited the debate suggested that the heavy ring rain may be responsible for the rings appearing young, circling back to the original notion that the rings are as old as the solar system after all. “I think it would be fascinating if the life time of the rings was only 100 million years or so and that their age was billions of years,” O’Donoghue told Space.com.

Will Jupiter’s storm ever end?
Home News Science & Astronomy
An enhanced image of Jupiter’s Great Red Spot, as seen by NASA’s Voyager 2 probe on July 7, 1979. (Image credit: NASA/JPL/Björn Jónsson/Seán Doran/ Flickr ( CC BY-NC-ND 2.0 )) The iconic Great Red Spot of Jupiter may disappear in the next 20 years, according to a researcher at NASA’s Jet Propulsion Laboratory (JPL) in California.
The massive storm — larger than Earth itself — was first spotted in 1830, and observations from the 1600s also revealed a giant spot on Jupiter’s surface that may have been the same storm system. This suggests Jupiter’s Great Red Spot (GRS) has been raging for centuries. In a recent story, Business Insider spoke with Glenn Orton, a lead Juno mission team member and planetary scientist at NASA Jet Propulsion Laboratory (JPL), about the giant storm’s fate.
According to Orton, the storm’s vortex has maintained strength because of Jupiter’s 300-400 mph (483-640 km/h) jetstreams, but like any storm, it won’t go on forever. “In truth, the GRS has been shrinking for a long time,” Orton told Business Insider, An illustration comparing the size of Jupiter’s Great Red Spot to that of Earth. While the reddish-hued storm is massive, it was once much larger. According to observations taken in the 1800s, the Great Red Spot was once about four times the diameter of Earth.
(Image credit: NASA/SwRI/MSSS/Gerald Eichstädt/Seán Doran/ Flickr ( CC BY-NC-ND 2.0 )) In the late 1800s, the storm was perhaps as wide as 30 degrees longitude, Orton said. That works out to more than 35,000 miles — four times the diameter of Earth. When the nuclear-powered spacecraft Voyager 2 flew by Jupiter in 1979, however, the storm had shrunk to a bit more twice the width of our own planet.
Data on Jupiter’s crimson-colored spot reveals that this shrinking is still occurring. As of April 3, 2017, the GRS spanned the width of 10,159 miles (16,350 kilometers), less than 1.3 times Earth’s diameter.The longest storm on Earth lasted 31 days, but Jupiter can sustain longer storms because the gas planet has tens of thousands of miles of atmosphere, and spins much faster than Earth.

Is 1 hour in space 7 years on Earth?
How long is 7 years on Earth in space? – The story is that 1 hour on that particular planet is equivalent to 7 years in space. Time dilation is real, but it’s completely unrealistic that it would have an effect anywhere near that in any realistic scenario. In practice, it’s a tiny fraction of a second, not many years.
Do humans age in space?
Time can appear to move faster or slower to us relative to others in a different part of space-time. That means astronauts on the International Space Station get to age just a tiny bit slower than people on Earth. Astronauts on long missions “may be vulnerable to unique stressors that can impact human aging,” a study found.
Loading Something is loading. Thanks for signing up! Access your favorite topics in a personalized feed while you’re on the go. Time feels like one of the only constants in life — it passes day after day at the same pace. Then Albert Einstein had to go and ruin that for us.
We’ve all heard the phrase that “time is relative,” but it can be difficult to wrap the mind around what that actually means. The phrase came from Einstein’s Theory of Relativity that joined space and time and created the idea of a fabric that permeates the whole universe: “space-time.” We all measure our experience in space-time differently.
That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. Public Domain The phenomenon is called ” gravitational time dilation,” In a nutshell it just means time moves slower as gravity increases. That’s why time passes slower for objects closer to the center of the Earth where the gravity is stronger. That doesn’t mean you could spend your life in a basement, just to outlive the rest of us here on the surface.

Time gets even weirder though. The second factor is something called “relative velocity time dilation” where time moves slower as you move faster. The classic example of this is the twin scenario. One twin blasts off in a spaceship traveling close to the speed of light, and one twin stays behind on Earth.
- When the space-traveling twin returns to Earth, she’s only aged a couple years, but she’s shocked to find that her Earth-bound sister has aged over a decade.
- Of course no one has performed that experiment in real life, but there’s evidence that it’s real.
- When scientists launched an atomic clock into orbit and back — while keeping an identical clock here on Earth — it returned running ever so slightly behind the Earth-bound clock.
Then time gets even more complicated because gravitational time dilation and relative velocity time dilation can happen at the same time. A good way to think about it is to consider the astronauts living on the International Space Station. Currently, an international crew of seven live and work aboard the ISS, orbiting Earth about every 90 minutes, according to NASA.
They’re floating about 260 miles above, where Earth’s gravitational pull is weaker than it is at the surface. That means time should speed up for them relative to people on the ground. But the space station is also whizzing around Earth at about nearly five miles per second. That means time should also slow down for the astronauts relative to people on the surface.
You’d think that might even out, but actually their velocity time dilation has a bigger effect than their gravitational time dilation, so astronauts end up aging slower than people on Earth. The difference isn’t noticeable though — after spending six months on the ISS, astronauts have aged about 0.005 seconds less than the rest of us.
That means that when former NASA astronaut Scott Kelly returned home in 2016 from his history-making, year-long stay on the ISS, he technically was 0.01 second younger than his twin astronaut brother — and now US senator — Mark Kelly who stayed on Earth. So the next time you find yourself wishing the weekend would last longer, stay low to the ground and move really fast.
It won’t feel like your weekend got any longer, but technically you may gain a teeny, tiny fraction of a fraction of a second. Remember, time is relative.
How old would I be on Mars if I was 11?
How old would I be on Mars? Enter your age in the box above, then click the CALCULATE button to see how old you’d be on the planet Mars. A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.

Why does it take Jupiter so long to complete its orbit around the Sun?
Kepler’s Third Law Compares the Motion of Objects in Orbits of Different Sizes – A planet farther from the Sun not only has a longer path than a closer planet, but it also travels slower, since the Sun’s gravitational pull on it is weaker. Therefore, the larger a planet’s orbit, the longer the planet takes to complete it.
Why is a year on Jupiter 12 years?
After all, everything in space is moving all the time, so there’s more going on than Jupiter crossing an invisible finish line. Jupiter is on average five times farther from the Sun than Earth, and it takes much longer to complete an orbit than our planet does, 12 years to our 1 year.
Does Jupiter tax around 12 years to orbit around the Sun?
Jupiter revolves or orbits around the Sun once every 11.86 Earth years, or once every 4,330.6 Earth days. Jupiter travels at an average speed of 29,236 miles per hour or 47,051 kilometers per hour in its orbit around the Sun.
What causes Jupiter to orbit the sun?
If You Think Jupiter Orbits the Sun, You’re Mistaken Jupiter does not orbit the sun Tech Insider If we picture the, we often picture our dominant star at the center of things, static and immobile as planets orbit circles around it. That picture makes things simple to understand, but technically it’s inaccurate.
- Take our largest planet, for instance.
- It doesn’t orbit the sun’s center — it orbits a spot in empty space between it and the sun called,
- This is because the sun doesn’t just exert gravity on Jupiter — Jupiter’s so big that its own pull affects how the moves, too.
- The sun is about 1,000 times more massive than Jupiter, and these two bodies affect one another proportionally according to distance and mass, so the amount Jupiter’s gravity pulls on is one-thousandth the amount the sun’s gravity pulls on Jupiter.
And Jupiter’s orbit takes 11.8 Earth years to complete, and the sun travels around the barycenter takes the same amount of time. The Sol-Jupiter barycenter sits 1.07 times the radius of the sun from the sun’s center, or 7 percent the radius of the sun from the surface.
- The sun also orbits this spot; if you were to look at the planetary plane from above, you’d notice a slight wobble as the sun moves around the, as this hypnotic NASA animation helps explain.
- That’s not just a cool fact to impress people at dinner parties — after all, who doesn’t love a person that begins sentences with “Well, technically.” — the practical application is that can look for a similar wobble in other stars and infer the existence of other massive celestial bodies.
And if we are getting technical, it’s worth noting that no other orbit the exact center of the sun, either. But the amount they affect the sun is so negligible that they effectively orbit the center, as their (our) respective barycenters are buried deep within the star’s burning plasma.
One of the reasons for that is due to Jupiter’s super-sized presence: If you piled all the other onto one side of an admittedly gigantic scale, then doubled that planet pile just for good measure, massive Jupiter would still outweigh all that. Let’s not despair, though. Not everything we’ve been taught is wrong! Learning more about the barycenters of orbits is a reminder that all things are connected and that all things influence one another — sometimes to a great degree, sometimes to one small, but always measurably.
Our solar system is not a series of spinning circles — think instead of a throbbing math cloud, pulsing as each element travels through its own orbit. We live in a, bound together, charting a fascinating shared path through space. An artist’s depiction of the solar system. Now That’s Amazing We’re discovering new stars all the time, but one of the biggest found so far is called, It’s a bright red supergiant about 1,700 times larger than our sun if you measure the amount of space it takes up; but it’s not very dense, and only carries about 30 times the sun’s mass. : If You Think Jupiter Orbits the Sun, You’re Mistaken
