Jupiterâs mass is two and a half times all of the other planets combined. Its density, however, is only one-fourth that of Earth. The reason for its low density is because the planet is a gas giant, along with Uranus, Neptune and Saturn. Jupiter is mainly composed of hydrogen and helium, although it may also have a rocky core composed of heavier elements. Unfortunately, the lack of oxygen in the atmosphere makes it highly unlikely that there are large amounts of water on the planet, quashing hopes that life could be found there.
