Rings of Saturn - Wikipedia
The rings of Saturn are the most extensive and complex ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, [1] that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material.
New Simulations Shed Light on Origins of Saturn’s Rings and ... - NASA
Sep 26, 2023 · Saturn’s rings today live close to the planet, within what’s known as the Roche limit – the farthest orbit where a planet’s gravitational force is powerful enough to disintegrate larger bodies of rock or ice that get any closer. Material orbiting farther out could clump together to …
