1,000 Jupiters According to multiple studies, around 1,000 Jupiters could fit into the Sun. This calculation was done using the volume of the Sun compared to the See full answer below.

How many Jupiter’s can fit in Earth?

Jupiter has a diameter of about 88,695 miles (142,800 kilometers) which is more than 11 times the diameter of Earth. It’s volume is over 1,300 times the volume of Earth. This means that Jupiter is so big that over 1,300 Earths could fit inside of it. Jupiter is so big that it weighs two and a half times the weight of all of the other eight planets put together!

How many of each planet can fit in the Sun?

From the vantage point of a human, our world truly is huge. However, in the grand, cosmic scheme of things, the Earth is but a drop in the solar bucket. The sun is a star at the center of the solar system, a sphere made up of hot plasma and magnetic fields.

Its diameter is about 1,392,000 km (864,000 miles), nearly 109 times larger than the Earth, and its mass is 330,000 times that of the Earth. In fact, by mass, the sun makes up over 99.86% of the solar system, whereas gas giants like Jupiter and Saturn comprise most of the remaining 0.14%. In order to comprehend the sheer scale of the sun, it’s worth asking the question: how many Earth-sized planets can you fit inside the sun? Volume-wise, you could fit nearly 1.3 million Earths into the sun (1.412 x 10 18 km 3 ).

How many Earths REALLY fit inside the Sun? (Scale Model)

That’s assuming all those millions of Earths are squished together with no empty space in between. But the Earth’s shape is spherical not a cube, so only about 960,000 Earths would fit inside the volume of the sun. Here’s how it would look like (approximately) if the Earth was a tiny blue marble: The sun is just an average-sized star, though.

1. For instance, the red giant Betelgeuse has a radius 936 times that of the sun, making it billions of times larger in volume than the Earth.
2. And that’s nothing.
3. VY Canis Majoris is thought to have between 1,800 and 2,100 times the radius of the sun.
4. Therefore, you could fit dozens of billions of Earths in some of the largest stars in the universe.

Earth is neither the largest nor the smallest planet in the solar system. Mercury (0.055 times Earth’s volume), Venus (0.85 times Eath’s volume), and Mars (0.151 times Earth’s volume) are all smaller than Earth. It would take 17.45 million Mercury-sized planets, 1.12 million Venus-sized planets, and 6.3 million Mars-sized planets to fill the sun, gaps not included.

• On the opposite end, you could fit 726 Jupiter-sized planets (1,321 times the volume of Earth) and 1,256 Saturn-sized planets (764 times the volume of Earth) inside a hollow sun, gaps not included.

How many Saturns can fit in the Sun?

Jupiter and Saturn – Moving on to the great gas giants, Jupiter and Saturn, the numbers start to go down or up in other cases. Jupiter is the biggest planet in our Solar System but pales when compared in size to the Sun and any other aspects. Jupiter has a diameter of around 142.984 km / 88.846 mi at the equator, and a diameter of about 133.708 km / 83.082 mi at the poles. Jupiter might seem impressive in these regards, but it would only take around 1.000 Jupiter-sized planets to fill the Sun. When it comes to Saturn, which is the second-largest planet in our Solar System, things start to change. Saturn has a diameter of approximately 120.536 km / 74.897 mi and a radius of around 58.232 km / 36.183 mi.

One of the first images taken by the ESA/NASA Solar Orbiter during its first close pass at the sun in 2020. (Image credit: Solar Orbiter/EUI Team/ ESA & NASA; CSL, IAS, MPS, PMOD/WRC, ROB, UCL/MSSL) The sun lies at the heart of the solar system, where it is by far the largest object,

It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun. The surface of the sun is about 10,000 degrees Fahrenheit (5,500 degrees Celsius) hot, while temperatures in the core reach more than 27 million F (15 million C), driven by nuclear reactions.

One would need to explode 100 billion tons of dynamite every second to match the energy produced by the sun, according to NASA, The sun is one of more than 100 billion stars in the Milky Way, It orbits some 25,000 light-years from the galactic core, completing a revolution once every 250 million years or so.

• The sun is relatively young, part of a generation of stars known as Population I, which are relatively rich in elements heavier than helium.
• An older generation of stars is called Population II, and an earlier generation of Population III may have existed, although no members of this generation are known yet.

Is Jupiter 100x bigger than Earth?

Jupiter is the 5th planet from the Sun, and the largest planet in the Solar System. How much bigger is Jupiter than Earth? Just to give you a sense of scale, Jupiter is 2.5 times more massive than all the rest of the planets in the Solar System combined.

Jupiter’s diameter is 11.2 times larger than Earth. In other words, you could put 11.2 Earths side-by-side to match the diameter of Jupiter. And Jupiter’s volume is even bigger. It would take 1321.3 Earths to fill up the volume of Jupiter. In terms of surface area, Jupiter is 121.9 times bigger than the Earth.

That’s how many Earths could be flattened out to cover the surface of Jupiter. Jupiter has 317.8 times the mass of the Earth. Even though Jupiter is an enormous, massive planet, it’s much smaller than the Sun. The Sun accounts for 99.86% of the mass of the Solar System.

• You could fit 109 Earths side by side to match the diameter of the Sun, and it would take 1.3 million planets the size of the Earth to fill it up.

Is Jupiter hot or cold?

With an average temperature of minus 234 degrees Fahrenheit (minus 145 degrees Celsius), Jupiter is frigid even in its warmest weather. Unlike Earth, whose temperature varies as one moves closer to or farther from the equator, Jupiter’s temperature depends more on height above the surface. This is because heat is driven not by the sun but by the interior of the planet. A comparison of the visible, near infrared, and thermal infrared views of Jupiter. The thermal-infrared image shows the heat from the planet’s surface, rather than the light reflected by the sun, and allows for greater understanding of the turmoil in the Jovian atmosphere.

(Image credit: Mike Wong, Franck Marchis, Christopher Go) Layers of gas Jupiter is made up predominantly of hydrogen, with some helium. Small traces of other gases also contribute to the planet’s composition, These gases fill the entire planet, descending all the way to the core. The surface, as identified by scientists, is the region where the pressure is equal to that at the surface of Earth, one bar.

But don’t be misled by the term; you can’t stand on Jupiter’s surface, because it isn’t solid. Below the surface, the gas becomes liquid and even plasma, all the way to the central core. Within the regions of gas, the temperature varies in the layers of Jupiter’s atmosphere,

1. From the surface to about 30 miles (50 kilometers) up, the temperature decreases as you ascend, ranging from minus 100 C (minus 150 F) to minus 160 C (minus 260 F).
2. In the next layer, the temperature increases with altitude, returning to up to minus 150 F again.
3. At the top of the atmosphere, temperatures can reach as high as 1,340 F (725 C), over 600 miles (1,000 kilometers) above the planet’s surface.

Heating sources Because Jupiter’s distance from the sun is an average of 484 million miles (778 million km), heat from the star is weak, though it does contribute. Much of the heating of the gases come from the inside of planet itself. Beneath the surface, convection from the liquid and plasma hydrogen generate more heat than from the sun.

Can a planet have 2 suns?

Artist’s impression of Kepler-16b, the first planet known to definitively orbit two stars – what’s called a circumbinary planet. The planet, which can be seen in the foreground, was discovered by NASA’s Kepler mission. Credit: NASA/JPL-Caltech/T. Pyle Study proves ground-based telescopes can search for planets with two suns. Astronomers have used a new technique to confirm a real-life Tatooine, the fictional planet with two suns that was home to Luke Skywalker in “Star Wars.” The planet, Kepler-16b, is about 245 light years from Earth, is a gas giant, and is roughly the size of Saturn Saturn is the sixth planet from the sun and has the second-largest mass in the Solar System. It has a much lower density than Earth but has a much greater volume. Saturn's name comes from the Roman god of wealth and agriculture. ” data-gt-translate-attributes=””>Saturn, Scientists already knew that the planet existed, but in a recent study, an international team of astronomers explained how they successfully applied a technique that hadn’t been previously used to observe a planet orbiting two stars. “It’s a confirmation that our method works,” said David Martin, co-author of the study and NASA Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals. ” data-gt-translate-attributes=””>NASA Sagan Fellow in The Ohio State University’s Department of Astronomy. “And it creates an opportunity for us to apply this method now to identify other systems like this.” The technique, called the radial velocity method, has long been used in astronomy. (The first planet ever found around a sun-like star was found using radial velocity – and was found using the same telescope astronomers used to find this one.) The radial velocity method involves analyzing the spectra of light produced by the stars. Astronomers gather spectra data through telescopes on the ground – in this case, from a telescope based in France, the Observatoire de Haute Provence. That spectra data graphs into a line, but the line “wobbles” as the planet orbits around the two stars, producing a shaky line in the spectra of light. The wobble indicates a planet is there, and astronomers can use it to derive a number of other pieces of information about a planet, including its mass. Measuring radial velocity is, Martin said, among the best tools astronomers have to identify exoplanets, or planets outside our solar system, But until this study, astronomers had not been able to use it to find planets outside our solar system that orbit two stars. The study was published this week in the Monthly Notices of the Royal Astronomical Society, In the past, such planets – known as circumbinary planets – were identified by monitoring when one star passed in front of the other. That method, known as the “transit method,” has identified 14 such planets, including Kepler-16b. The first confirmed circumbinary planet was described in a paper in 2011; others have followed. But until this paper, none had been found using radial velocity. “What people had faced was that having two sets of spectra from two stars makes it really tricky, and people were struggling to get enough precision to see the wobble caused by the planet,” Martin said. “And we got around that by making a survey of systems with two stars that orbit each other where one star is big, and one is quite small.” The survey, called Binaries Escorted by Orbiting Planets, or BEBOP, was established specifically to search for planets like this one. One of Kepler-16b’s stars is about two-thirds the mass of Earth’s sun, and the other is about 20% the mass. Astronomers had been watching this system since July 2016. Proving that measuring radial velocities can identify planets that orbit two stars, Martin said, opens the door for the technique to be applied more broadly. That is important to astronomers for a number of reasons, but a big one is that planets that orbit two stars tend to exist at a distance that would make them good candidates for life. “These planets are frequently found in the habitable zone, at a distance from the stars where you would expect to find liquid water,” Martin said. Kepler-16b, which is made primarily of gas, is not likely to be a candidate where life could be found, Martin said. But using the radial-velocity method could help astronomers find other similar planets. Reference: “BEBOP III.

What is the biggest star ever?

What is the biggest star in the universe? – The largest known star in the universe is UY Scuti, It has an estimated radius of 1.188 billion kilometers. If UY Scuti were the center of our solar system, its photosphere, or outer shell, would reach just past the orbit of Jupiter.

It is a red hypergiant, meaning it has an enormous mass and luminosity. These types of stars are harder to find, however, because of their short life spans. Unlike other stars which last for billions of years, hypergiants only exist for a few million years. UY Scuti was discovered in 1860 by German astronomers; at the time, it was named “BD-12 5055.” This star can be found near the center of the Milky Way, around 9,500 lightyears away from Earth.

It is a part of the constellation Scutum. Space photos: Stunning images you have to see Just Curious: We’re here to help with life’s everyday questions

Can a planet have 3 suns?

Planets have been found in multiple-star systems, but they often orbit only one of the stars. Planet KOI-5Ab, for example, also has three suns in its skies, but it orbits around only one of them, gravitationally bound to that one star as it interacts with its neighbouring stars.

What is bigger than the Sun?

UY Scuti – This is the largest ever known star in the Universe! UY Scuti is a variable red hypergiant with a radius around 1,700 times larger than our Sun. Basically, if we can imagine in more simpler terms, then around 5 billion suns could fit inside the UY Scuti! Surprisingly, this biggest star has 23.0 solar masses and it’s 47% cooler than the Sun.

It was first discovered back in 1860. V766 Centauri’s primary star Aa is a yellow hypergiant with a magnitude of 6.90, 959.8 million miles of diameter, and its mass is 13.0 solar masses. This too has temperature 21 percent cooler than the Sun. KY Cygni is the third largest star in the universe which is a red supergiant which was first discovered in 1930.

According to research, the KY Cygni measures close to 1,033 times the width of the sun.

How many Mercury’s can fit in Earth?

Mercury Mercury is the first planet from the Sun. It is not very easy to observe since it is always close to the Sun in the sky. Even when best placed, it is close to the horizon and only visible for a few hours after sunset or before sunrise. Named after the winged messenger of the gods, the planet speeds around the Sun once every 88 days.

However, it spins on its axis very slowly – once every 58.6 days. This is exactly two thirds of its orbital period. Mercury is a small, rocky world. It is only about as wide as the Atlantic Ocean and 18 Mercurys would fit inside the Earth. Mercury is very like the Moon. Its surface is covered with impact craters.

It has no atmosphere and no water. The noon temperature at the equator can soar to 450°C but the nights are extremely cold, below -180°C. There may be some water ice in the deep, dark craters near the poles. Mercury is surprisingly dense. It is thought to have a large iron core that fills most of Mercury’s interior.

It also has a surprisingly strong magnetic field. So far, less than half of the surface has been imaged at close range by the Mariner 10 spacecraft. ESA and Japan are planning to send two orbiter spacecraft to Mercury in 2013. The BepiColombo mission is named after a famous Italian mathematician and scientist.

Can Jupiter be habitable?

Potential for Life – Jupiter’s environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to. While planet Jupiter is an unlikely place for living things to take hold, the same is not true of some of its many moons.

What’s the largest planet in the universe?

The largest planet in our solar system is Jupiter with a radius of 43,441 miles. The largest planet in the universe is an exoplanet called ROXs 42Bb, with an estimated radius 2.5x larger than that of Jupiter.

Why is Jupiter so bright now?

Jupiter is the biggest planet in the solar system. If the mass of all planets combined together is compared to that of Jupiter, the planet is still more massive which is one of the reasons why it is bright at all times of the year.

Can humans go to Venus?

1. So when are we going back? Astronomers on Monday, which may be a possible sign of life.
2. That has some planetary scientists itching to return to the sun’s second planet, especially and other destinations.
3. If this planet is active and is producing, and there is something that’s making it in the Venus atmosphere, then by God almighty, forget this Mars nonsense,” said Paul Byrne, a planetary scientist at North Carolina State University.

“We need a lander, an orbiter, we need a program.” Venus is not easy to visit. Its carbon-dioxide-rich atmosphere is 90 times as dense as ours, and surface temperatures average 800 degrees Fahrenheit. Its surface pressure is intense enough to crush some submarines.

1. But that hasn’t stopped human space programs from trying.
2. Launched by governments on Earth have tried to visit Venus in one way or another.
3. Here are highlights from past journeys to Venus, as well as the prospects for a speedy return to the planet to find out what’s going on in those clouds.
4. In 1961, the Soviet space program began trying to explore Venus.

In the decades that followed, it shot dozens of spacecraft toward the world sometimes known as Earth’s twin. While Soviet exploration of Venus started with many misfires, the country became the first to land a spacecraft on another world, and not long after, the first to take photos from the surface of another planet.

Their engineering achievements were significant even by modern standards. After seeing their first round of spacecraft sent into the atmosphere squashed like tin cans, the Soviets realized just how extreme the pressure on Venus was. This trial and error led to the construction of five-ton metal spacecraft built to withstand, even if for just an hour, the immense surface pressures.

Venera 4 in 1967 became the first spacecraft to measure the atmosphere of another planet, detecting large amounts of carbon dioxide that cause the ceaseless Venusian greenhouse effect. A view of the surface of Venus captured by the Soviet Union’s Venera 14 lander in 1982.

• Russian Academy of Sciences/Ted Stryk Then in 1975, the country’s Venera 9 probe became the first to take images from the surface of another planet.

The world officially met Venus. and later missions sent back revealed a planet that was truly like no other: cracked terrain beneath, The planet we thought might have been covered in oceans and akin to our own was instead an alien world with poison rain.

Later missions in the Venera series into the 1980s gave scientists a better understanding of the planet’s geological processes. Venera 11 and 12 both detected large amounts of lightning and thunder as they traveled to the surface. Venera 13 and 14 were both equipped with microphones that documented the sounds of their descent to the surface, making them the first spacecraft to record audio from another planet.

In 1985 the Soviet Union concluded its Venus encounters with the twin Vega spacecraft, which each released large balloons loaded with scientific instruments, demonstrating the potential for probes that could float in the planet’s clouds. The slowed pace of the Soviet space program toward the end of the Cold War halted launches to Venus.

While the Russian space program has, its concepts have not moved off the drawing board. A global view of the surface of Venus made mostly from data captured by the Magellan spacecraft in 1991. Credit. NASA/JPL While Mars has always seemed like the apple of the eyes of American space planners, the Mariner and Pioneer programs of the 1960s and ’70s made time for Venus.

Mariner 2 was the first American spacecraft to make it to Venus, in 1962. It determined that temperatures were cooler higher in the clouds, but extremely hot on the surface. In 1978, the Pioneer missions gave American researchers a closer look. The first of the pair orbited the planet for nearly 14 years, revealing much about the mysterious Venusian atmosphere.

It also observed the surface was smoother than Earth’s, and that Venus had very little or perhaps no magnetic field. A second Pioneer mission sent a number of probes into Venus’s atmosphere, returning information on the structure of the clouds and radar readings of the surface. NASA’s Magellan entered into orbit in 1990 and spent four years mapping the surface and looking for evidence of plate tectonics.

It discovered that nearly 85 percent of the surface was covered in old lava flows, hinting at significant past and possible present volcanic activity. It was also the last of the American visitors, although a number of NASA spacecraft have used Venus as a slingshot as they set course for other destinations.

• Venus Express was launched by the European Space Agency in 2005.
• It orbited the planet for eight years and observed that it still may have been geologically active.
• The planet’s only guest from Earth right now is, which was launched by Japan in 2010.
• The probe missed its meeting with Venus when its engine failed to fire as it headed into orbit.

By 2015, the mission’s managers had managed to steer it on a course to orbit and study the planet. It has since transformed how scientists view our clouded twin. In its study of the physics of the dense cloud layers of Venus, the mission has revealed disturbances in the planet’s winds, as well as equatorial jet streams in its atmosphere.

PLANET-C Project Team/JAXA Many missions back to Venus have been proposed, and some space agencies have declared ambitions of visiting the planet. But it’s hard to say whether any will make the trip. India’s space agency has proposed a mission called Shukrayaan-1, which will orbit the planet and primarily focus on the chemistry of the atmosphere.

Peter Beck, the founder of Rocket Lab, a private company started in New Zealand that has launched about a dozen rockets to space, has recently spoken of, NASA has considered a number of Venus proposals in the past decade, including two in 2017 that were finalists of NASA’s Discovery program, which has previously sent explorers to the moon, Mars, Mercury and other destinations.

And Venus proponents may have a new advocate inside NASA. Lori S. Glaze, the principal investigator of Vici, is now the planetary science division director at NASA. The agency will have another chance to pick a Venus mission for funding in the next round of its Discovery program.

Two Venus spacecraft, named and, are competing against proposed missions to or, NASA may select two of the four finalists. And there could be other possibilities for visitors to Venus. “We should also recognize that Venus is a planetary destination we can reach with smaller missions as well,” said Thomas Zurbuchen, the head of NASA’s science mission directorate.

What’s the coldest planet?

What is the coldest planet in the Solar System? – Sejal, aged seven, Bangalore, India The planets in our Solar System are heated by the Sun. Here on Earth, we are about 100 million miles away from the Sun – a distance that provides the perfect temperature for life.

You might think, then, that the coldest planet in the Solar System would be Neptune, as it is the furthest away from the Sun’s warmth. Neptune is an incredible three billion miles away from the Sun. However, the coldest planet is not Neptune, but Uranus – even though Uranus is a billion miles closer to the Sun than Neptune.

Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃, The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. Knocked sideways The reason why Uranus is so cold is nothing to do with its distance from the Sun.

Billions of years ago, something big crashed into Uranus with so much force that it tipped the planet over onto its side. Uranus still rolls around the Sun on its side today. The impact of the crash also let some of the heat that was trapped inside Uranus escape. The heat inside planets is left over from when they were formed.

Planets are made when smaller chunks of rock smash together, building the full planet piece by piece over many millions of years. Every time these rocks smash together, the planet gains a little more heat. If you clap your hands together for a long time they will start to feel hot – the same thing happens with planets.

• Neptune wasn’t hit by a huge asteroid like Uranus was, so it has been able to hold on to more of its heat.
• You might also be surprised to learn that the closest planet to the Sun, Mercury, can also be extremely cold.
• While the side of Mercury facing the Sun is more than 400℃, the side facing away from the Sun is nearly -200℃.

The reason for this is that Mercury does not have any atmosphere, unlike Earth. An atmosphere like ours acts like a blanket, holding heat in and spreading it all around. Because it does not have this blanket, the front side and the back side of Mercury can have very different temperatures.

Measuring temperatures in space For some nearby planets like Mars, we can send probes to study the atmosphere directly from the planet’s surface. However, we haven’t been able to do this for distant planets such as Neptune and Uranus. Instead, we have to work out how cold they are by measuring their temperature from here on Earth.

We do this by studying the light from the planet, which can tell us the types of atoms and molecules which make up the planet’s atmosphere. This information lets us know exactly what the temperature of the planet is: the atoms and molecules act as a kind of temperature “fingerprint” for the planet.

• While these planets in our Solar System are incredibly cold, there are even chillier places in the universe.
• The coldest of all is the Boomerang Nebula, a cloud of dust and gas 30 million billion miles away from us.
• There, the temperature reaches -272℃.
• Nothing in the Universe can be colder than -273℃, because at that temperature the tiny particles and atoms that everything is made of basically stop moving, and once that happens it’s impossible to go colder.

This temperature is known as absolute zero, This means it is unlikely that we will ever find anywhere in the Universe colder than the Boomerang Nebula. Article written by Professor Brad Gibson Curious Kids is a series by The Conversation that gives children the chance to have their questions about the world answered by experts.

How hot is the moon?

How cold is the Moon? – There is almost no atmosphere on the Moon, which means it cannot trap heat or insulate the surface. In full sunshine, temperatures on the Moon reach 127°C, way above boiling point. There are 13 and a half days of high temperatures followed by 13 and a half days of darkness, and once the Sun goes down the temperature at the bottom of craters can plummet to -173°C.
