Rings.....................................................................................Rings are 270,000 km in diameter,
but only a few hundred meters thick. Particles are centimeters to decameters in size and are ice
(some may be covered with ice); there are traces of silicate and carbon minerals. There are four
main ring groups and three more faint, narrow ring groups separated by gaps called divisions.
