Does Jupiter have a solid surface?

Jupiter does not have a solid surface and although there is a small solid core, there is nothing like a planetary surface. It is under an enormous pressure caused by the mass of gas that makes up the bulk of the planet. The atmosphere of Jupiter is ninety percent hydrogen. The remaining ten percent is almost wholly made up of helium, though there are small traces of other gases inside. Like the sun, Jupiter is composed of hydrogen and helium.

The atmosphere of Jupiter is ninety percent hydrogen. The remaining ten percent is almost completely made up of helium. These gas layers form layers that extend downward. Because there is no solid ground, Jupiter's surface is defined as the point where the atmospheric pressure is equal to that of Earth. Trying to stand on the surface would be impossible since it is merely another layer of gases.
