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.
The atmosphere on Titan contains a lot of the gas nitrogen, like what we have here on Earth. Scientists believe that Titan may have liquid water on its surface, which would be an exciting discovery if it turns out to be true. The Cassini space mission will land a probe, or special landing craft, on Titan to try and answer some of these questions. Saturn was named for the Roman god of agriculture. In Roman mythology Saturn was the father of Jupiter.
