Jupiter Jupiter is a large gas planet whose clouds change colors daily. This planet is made mostly of hydrogen and helium gases. Jupiter gives off two times more heat than it gets from the Sun. Jupiter Jupiter is the fifth planet from the Sun and is the largest one in the solar system. If Jupiter were hollow, more than one thousand Earths could fit inside.
Gas giants are also very much larger than terrestrial planets.
It has been known since prehistoric times. Jupiter Jupiter is the largest planet in the solar system. In fact, it is more massive than all the other planets and moons in our solar system combined. This heat, produced when Jupiter formed, slowly escapes into space. Jupiter's Ring System Jupiter's ring was discovered by Voyager 1 in a single image that was targeted specifically to search for a faint ring system.
