Ring System

General Description
A ring system is a disc or ring orbiting an astronomical object that is composed of solid material such as dust and moonlets, and is a common component of satellite systems around giant planets. A ring system around a planet is also known as a planetary ring system.

The most prominent and most famous planetary rings in the Milky Way are those around Saturn, and J1407B. Ring systems may also be found around other types of astronomical objects, including minor planets, moons, and brown dwarfs.
