rings of Saturn [′riŋz əv ′säd·ərn]
(astronomy) Circular rings that encircle the planet Saturn at its equator; there are four main regions to the ring system; theory and observations indicate that the rings are composed of separate particles which move independently in the four series of circular coplanar orbits.
