Saturn's Rings
Summary
Galileo discovered Saturn’s Rings in 1610 and since then it has been a long and intriguing journey of discovering newer and interesting things about them. Saturn’s Rings stretch over a 150000 miles across and they are composed of countless chunks of ice. These chunks range in sizes and they constantly collide gently with each other. Different theories exist regarding the origin of these rings. The Saturn is orbited by a retinue of moons. One of them, Mimas, orbits just outside the rings. Over a period of millions of years, the gravity of Mimas has carved out a gap in the rings called the Casssini division. The Casssini spacecraft has been orbiting Saturn since 2004 and it has returned the best images of Saturn and its ring system.
