Saturn is the second largest planet in the Solar System. Cloud belts can be seen crossing Saturn, although these are not as easy to see as those of Jupiter. There are at least 21 moons going around it. The largest of these is Titan, which is a lot bigger than Earth's moon. The rings around Saturn make it one of the most beautiful sights in the sky. These rings can be seen through a small telescope. They are made up of millions of tiny icy particles.
