The ring systems of planets are collections of ice, dust, and rock particles that orbit around a planet. These rings can vary in size and thickness, and they are most commonly found around the gas giants like Saturn, Jupiter, Uranus, and Neptune. Saturn is famous for its bright and extensive rings, which are made primarily of ice particles. The rings are formed from debris that may have originated from moons, comets, or asteroids that were torn apart by a planet's gravity. The particles in the rings can range from tiny grains to large boulders, and they often have complex structures, including gaps and waves caused by gravitational interactions with nearby moons.
