Saturn is perhaps one of the most beautiful objects in the Solar System with its many interesting features such as its twenty known orbiting satellites , its 6 x 10^26 kg mass (95 times the mass of Earth), and of course, probably the most studied feature of Saturn, its rings. Saturn's rings were a phenomenon that stumped astronomers ever since Galileo first saw them in 1659.

Today the rings have been studied extensively and almost all is known about them, or at least thought to be known. The rings have many interesting aspects such as the varying opacities, thicknesses, widths, compositions, many thousands of individual ringlets and not just one or two rings as it appears from telescopes, and strange divisions in the rings apparently devoid of any particles. There have also been some very interesting recent discoveries with the help of Voyager 2 which include strange spoke like images on the rings and spiral density waves in the ring system.
