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.
