Quizplus · Accepted Answer

Scientists believe that Saturn's rings are either remnants of a moon that never formed or a moon that was torn apart by the planet's tidal forces. This hypothesis is supported by the fact that the material in the rings is mostly icy and rocky particles that are similar in composition to the material that makes up Saturn's moons. Additionally, the rings are located in the same plane as Saturn's equator, which suggests that they may have formed from the debris of a moon that was torn apart along its equator.
