Do other planets aside from Saturn have rings?
Yes, there are other planets in the Solar System that have rings besides Saturn.
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.
Neptune's rings are composed of rocks and dust, each one is a different thickness, and have different compositions of rocks and dust. They are made up of at least 20% dust, but some of the rings can contain up to 70% dust.
