16. Ring Moon Interaction
The gravity from moons can change the orbits of ring particles by transferring momentum
At resonances, moons excite waves and can also truncate the ring creating an edge or gap
Moons not big enough to open a gap create propeller structures
Meteorite bombardment of small moons creates dusty rings
Volcanic eruptions on Enceladus creates Saturn’s E ring
