n. (context astronomy English) The combined system or structure formed by all of the rings orbiting a planet
Wikipedia
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 planetary rings in the Solar System are those around Saturn, but the other three giant planets ( Jupiter, Uranus, and Neptune) also have ring systems. Recent evidence suggests that ring systems may be found around other types of astronomical objects, including minor planets, moons, and brown dwarfs.
