Do other planets aside from Saturn have rings?

The planets Jupiter, Uranus, and Neptune are the other planets in the Solar System having rings.

Jupiter's rings were discovered by the Galileo space probe during its 2002 flyby. They are composed of dust that is propelled into orbit around the planet when a meteor strikes one of Jupiter's moons.

Uranus has 13 distinct rings that are only a few kilometers thick; these rings are made up of chunks of rock that most likely originated from stray moons that got too close to the planet and were crushed by the planet's gravity.

The materials that make up Neptune's rings are rocks and dust; the composition of the two components varies from one ring to the next, with the minimum amount of dust being 20% and as much as 70% in some of the rings.

Yes, other planets aside from Saturn have rings. Jupiter, Uranus, and Neptune also have rings, although they are not as prominent or well-known as Saturn's rings.
