Some moons are so small that only 53 have actually been given names.
One of the most famous moons of Saturn is called Enceladus. It is called the ocean moon as it has been seen spraying jets of water vapour and ice into space. It has been founds to have an ocean which covers the planet hidden below a thick crust of ice. Another moon, Mimas, might also have water on it's surface.
As well as the moons, Saturn also has a series of rings which are made of small rocks, dust and ice. Most of these objects are microscopic, but there are some rocks in the rings which have diameters of hundreds of metres. It is thought that the orbit of Saturn's moons give the rings their shape. Especially the gaps in between them.
