Rings of Saturn
The rings of Saturn is the name of the rings around the planet Saturn. They consist of many small particles, ranging in size from microscopic to the size of a bus (or bigger) that form clumps that in turn move around Saturn. The particles in the rings are made almost entirely of water ice, with just a small amount of dust and other chemicals. There are some gaps in the rings. The moon Pan causes the gap called the "Encke gap" in Saturn's A ring. The Cassini Division, discovered by Giovanni Domenico Cassini, is a gap between the A ring and the B ring.
