Ring system - Wikipedia
WEBA ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as gas, dust, meteoroids, planetoids or moonlets and stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as of Saturn, or circumplanetary disks.
