Is Jupiter a hollow planet?

Because there is no solid ground, the surface of Jupiter is defined as the point where the atmospheric pressure is equal to that of Earth. At this point, the pull of gravity is almost two and a half times stronger than it is on our planet.

Why is Jupiter so big?

Why is Jupiter so Big? Jupiter is so big because it is the oldest planet in our Solar System. It formed around one million years after the Solar System.

Is Jupiter too big?

The largest planet in the solar system, the gas giant Jupiter is approximately 318 times as massive as Earth. If the mass of all of the other planets in the solar system were combined into one “super planet,” Jupiter would still be two and a half times as large.

How much does a 100 pound person weigh on Jupiter?

240 pounds
If you weigh 100 pounds on Earth, you would weigh 240 pounds on Jupiter (assuming you could find someplace to, well, stand).

The most probable cause for Jupiter being so big is because back in the day of the early solar system, Jupiter and the sun were basically it, other than a huge amount of rocks. Jupiter accumulated enough gas to be very massive, but it didn’t reach the critical mass to become a star.

Could a Jupiter-sized planet be nearby?

And here’s another fun fact: Jupiter’s gargantuan bulk gives the sun a slight — but noticeable — wobble. So if scientists ever detect that kind of tottering motion in a far-off star, it could mean that a Jupiter-sized planet is nearby. Astronomers have been keeping a constant eye on Jupiter’s Great Red Spot since 1830.

Is Jupiter the largest planet in the Solar System?

Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter’s stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.

Is Jupiter shrinking or gaining mass?

If anything, it would be gaining mass (very slowly by a miniscule negligible amount) due to the millions of asteroids and comets which collide with it. It is said that Jupiter is shrinking at the rate of 2cm per year.
