The effects of orbital resonances are seen dramatically in the structure of the rings of Saturn. Describe and explain these effects
What will be an ideal response?
A ring particle with an orbital period that is an integral fraction of one of the moons will be pulled out of that orbit. The effects of these resonances with certain moons, such as Mimas, produce spaces between rings where few ring particles are found. Resonances also produce sharp, defining edges to some rings, such as the A ring.
