These beautiful rings comprise millions of icy particles ranging in size from dust to large boulders. The particles undergo an intricate dance as they orbit Saturn - the gravity of nearby moons causes the ring particles to bump into each other and create interesting patterns in the rings, such as waves and wakes. The Saturn ring system also includes ring gaps, narrow ringlets, spokes, diffuse rings, and sharp ring edges. Fundamental questions remain about Saturn's rings. Why are the rings there at all? How did they form? How old and how stable is the ring system, and how does it maintain itself? So far, we only have bits and pieces of answers. The Cassini mission to Saturn will provide a wealth of information to help answer many of these puzzling questions about Saturn's rings.
