Unlike other ring systems that were given proper names, Greek letters were primarily used to name the rings of Uranus, particularly the main rings. 1  Îµ ring (epsilon) â Is the brightest and the densest of the 13 rings of Uranus.
The other planets in the Solar System that have rings are Jupiter, Uranus, and Neptune. Jupiter's rings are made up of dust that gets thrown into orbit around the planet when a meteor hits one of Jupiter's moons. The rings were discovered by the Galileo space probe when it passed by in 2002. Uranus' rings are made up of chunks of rock that most likely came from stray moons that got too close to the planet, and were crushed by the planet's gravity. The planet has 13 distinct rings that are only a few kilometres thick.
