Saturn's Ancient Rings
How old are Saturn's rings? No one is quite sure. One possibility is that the rings formed relatively recently, perhaps only about 100 million years ago when a moon-sized object broke up near Saturn. Evidence for a young ring age includes a basic stability analysis for rings, and the fact that the rings are so bright and relatively unaffected by numerous small, dark meteor impacts. New evidence, however, raises the possibility that some of Saturn's rings may be billions of years old.
