"In our solar system, planetary rings are found around all the giant planets, showing spectacular variety. Jupiter's thin ring system is composed mostly of dust... Uranus has ten narrow, sometimes eccentric rings and a family of dust bands... All the ring systems have moons interspersed, which sculpt, collect, and release ring material. Moons are the likely parents of the present rings, ground down by meteorites and destroyed randomly to produce the relatively short-lived ring systems. Thus, we observe the natural stochastic results of birth and death processes when we examine the rings closely. Ring systems are relatively nearby and provide a natural laboratory for phenomena in flattened disks, including the nebula around our Sun that gave rise to the planets."
