Can rocks in Saturn's rings fall into the planet below?

Best Answers

The ice and rocks currently in the rings are all in relatively steady orbits. They've been there for millions of years, and any without a steady orbit would have fallen in already. read more

Some of Saturn's moons, and some of the larger rocks in the rings act as "shephard moons" keeping the other objects in place. Orbits of any of the ice or rocks can certainly be perturbed, but unless it's a big perturbation, they'll get shepharded back into place. read more

There is a certain distance from planets called the Roche Limit. Moons can form outside of this limit, but inside, tidal forces are so great that they prevent particles from forming into moons under their own gravity. For instance, our moon is outside Earth's Roche Limit. Saturn's rings, on the other hand, are inside. read more

Walking would be an inappropriate description of anything you might do near Saturn's rings which, according to Wikipedia, consist of countless small particles, ranging in size from micrometres to metres, that orbit about Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material. read more
