The planet with the most visible rings is Saturn. Its rings are an iconic feature that sets it apart from other planets in the solar system. Composed mostly of ice particles, along with some rock debris, Saturn's rings vary in thickness and can span up to 175,000 miles from the planet's center. The rings are thought to be remnants of moons, comets, or asteroids that have broken apart due to Saturn's gravitational pull. While other gas giants like Jupiter, Uranus, and Neptune also have ring systems, none are as bright and prominent as Saturn's.
