Answer Hello Kai… The Cassini Division is the result of orbital resonances with Mimas. Much of the fine structure within rings is governed by orbital resonances with the planet’s moons. The Cassini division is in a 2:1 resonance with the moon Mimas. Mimas orbits every 22h, Iceballs in the Cassini Division orbit every 11h.Every 2 orbits, iceballs in the Cassini Division get tugged towards Mimas, clearing a gap. Let me know if I can clarify anything, or if you have further questions.
