Like Jupiter, it is a Gas Giant and so its visible surface is not solid. It is most well known for its dramatic and beautiful ring system. The rings are not solid, but are made up of many millions of small lumps of ice and rock, varying from a few centimetres to several metres across. These are all orbiting around Saturn together.
Although they look very impressive, the rings are only about 1 km thick, compared to 250,000 km in diameter!
The first space-probe to go to Saturn was Pioneer 11 in 1979, but there have been several others since.
