For ages, Saturn was thought to be the only planet in our solar system with a ring system. But in recent years ring systems have been discovered around Jupiter, Uranus and Neptune as well. âThere are various theories about planetary rings, like the fantastic rings around Saturn, but we cannot say for sure how they are formed,â explains Lattis. One theory is that the rings formed at the same time as the planet and its major moons. In this case, if material is close to the planet, the planetâs gravitational pull is too strong to coalesce into a moon and the particles that would otherwise form a moon spread out in orbit around the planet as a ring.
