I am once again asking you for a random fact.

[ Still from that series ] Suppose a planet with a moon orbiting around it. If this moon get closer to the planet so that it's within the "Roche limit" of the planet, the gravitational force of the planet will disintegrate the moon creating a ring around the planet. As I understand it, Roche limit is the distance within which orbiting objects tend to scatter around the planet/star/whatever but outside this limit objects tend to come together. This is one of the theories that explains why Saturn has rings around it; An old moon trespassing Saturn's Roche limit.
