Saturn Ring
Galelio Galelli , the man who discovered Saturn’s rings.
But how these rings were composed ? Several hypotheses exist as to the how Saturn's rings were formed. Some scientists think that passing comets or asteroids were snagged by the planet's gravity and broken up before reaching it.
Another possibility is that the rings were once large moons that spiraled into the planet. Saturn has at least 62 moons. Only one (Titan) is large; the rest are small bodies. Only 13 of the moons are larger than 30 miles (50 km). The gravity of these moons affects the structure of Saturn's rings, but also offer insight into possible formation methods. If the icy outer layers were stripped away, leaving the core to crash into Saturn, the result would be rings dominated by nearly pure water-ice.
