... Like Jupiter, it is a Gas Giant and so does not have a solid surface. It is famous for its dramatic and beautiful rings. 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 Sa ...
