If you blow all of Jupiter’s gas away, will Jupiter disappear? Or is there something left?

In our solar system, there are four gaseous planets, they are Jupiter, Saturn, Uranus and Neptune. Among them, Jupiter is the largest of the eight planets in the solar system, and its rotation speed is also the fastest.

Its mass is very large, 2.5 times the total mass of the other seven planets, accounting for 70% of the total mass of the solar system.


And its volume is also very large, diameter is one tenth of the sun, the solar system is worthy of the name of “cell phone.”.

If you look at the picture below, you can deeply feel the “power” of “cell phone”.

Since Jupiter is a gas giant, if all of its gas is blown away, will Jupiter disappear?


Let’s first look at the structure of Jupiter. Galileo was the first to observe Jupiter. He saw Jupiter and its four surrounding moons through a telescope. Later, astronomers used more advanced telescopes to observe other details of Jupiter.

Jupiter is very bright, the surface of the great red spot and other structures can be seen. Although we have observed the general appearance of Jupiter, the details are not clear. With the advent of the space age (on October 4, 1957, the former Soviet Union launched the world’s first man-made satellite, marking the entry of mankind into the space age), scientists began to really study Jupiter.


NASA pioneer No. 10 flew over Jupiter in 1973 and became the first spacecraft to observe Jupiter in close range. It passed through the dangerous asteroid belt and the strong radiation area around Jupiter. It also brought back the close-up image of Jupiter and observed Jupiter’s magnetic field, radiation belt, atmospheric structure, etc., as well as Jupiter’s south pole.

After that, the Voyager and Galileo passed, and in 2011, the United States launched the Juno probe.

From the results of Juno, people know that Jupiter’s atmosphere is composed of 75% hydrogen and 24% helium, so it is very cold, with an average temperature of – 148 ℃. Jupiter’s pressure is very high, and hydrogen exists in liquid form under great pressure.


Jupiter has a stone core. Its temperature is different from that of the surface. It can reach thousands of degrees Celsius, even higher than that of the sun’s surface. Surrounding the core is a slightly less dense outer core composed of metallic hydrogen and heavy elements.

In general, the structure of Jupiter from the outside to the inside is first hydrogen rich atmosphere, then liquid hydrogen, and then with the increase of depth, the metal hydrogen layer is formed, and then the outer core is composed of heavy elements and metal hydrogen, and the innermost is the stone core.


We all know that as long as the mass of the celestial body is large enough, the velocity of gas molecules can not escape from the celestial body, and the larger the mass of the celestial body is, the more gas molecules can be retained.

Assuming that the gas in Jupiter’s outer layer will be blown away, will solid hydrogen and metallic hydrogen?

Xiao Bian thinks that the answer is of course, because no matter which one of them needs to maintain high pressure, if the peripheral gas is blown away, the pressure will disappear, and these substances will be gradually released.


This is like the gas in the gas tank. When the pressure decreases, the liquefied gas will be released and become gas. Solid hydrogen and metallic hydrogen will also be converted into gaseous hydrogen and eventually disappear into the universe, leaving a Jovian stone core.

So if you blow all of Jupiter’s gas away, Jupiter will have a rocky core left.


So although Jupiter is a gas giant, it has a stone core. Even if the gas is gone, the core will always exist and will not disappear completely.
