The gaps in Saturn's rings are caused by the many moons that circle the giant planet. The moons act to keep the rings lined up in the beautiful patterns you see here. One of the bands in Saturn's rings is even braided, much like a pigtail. The Voyager mission sent back pictures of this amazing feature. In Saturn's Rings You can clearly see the divisions in Saturn's rings in this picture.
Scientists believe the spokes are caused by the very strong magnetic field around the planet.
Saturn has at least eighteen moons, more than any other planet in our solar system. The Voyager missions took pictures of what might be at least six more moons, but we will have to wait for the Cassini mission for more information. The many moons of Saturn play an important part in keeping the shape of Saturn's spectacular rings. One of Saturn's most interesting moons is Titan. Titan has a very thick atmosphere, or blanket of air, surrounding it.
