Answer to Question 1

Saturn's rings consist of small icy objects, of average size that of a snowball. They orbit independently in a narrow band a few tens of meters thick. From Earth there appear to be three main rings, with a notable gap called the Cassini Division caused by gravitational resonance with a moon. In reality, there are several more small and/or partial rings.
