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
