Jupiter is the fifth planet from the Sun. It is a gas giant, which means it is made of gas. It is the biggest planet in the Solar System. It is named after one of the mythological Roman gods.

By 2003, 63 moons had been found around Jupiter. It has 16 big moons. The four biggest moons are the Galilean moons; they are named Io, Europa, Ganymede and Callisto.

Jupiter's atmosphere and size gives it very high ground pressure levels. If a space craft was sent into Jupiter, it would be crushed in seconds. This is the main reason why so little is known about what is under its atmosphere.
