A)having a very reflective, icy surface that is heavily cratered.
B)orbiting in a highly elliptical orbit, far from Saturn.

E)being the only major moon of any planet not in synchronous rotation.

Question

Quizplus · Accepted Answer

Rhea does have a very reflective, icy surface that is heavily cratered, as observed by spacecraft such as Cassini. Option B is incorrect as Rhea's orbit is actually quite circular. Option C is true, with the leading hemisphere being darker due to accumulation of debris from Saturn's E-ring. Option D is incorrect as Rhea is actually less dense than some of Saturn's other moons. Option E is true, as Rhea is not in synchronous rotation with Saturn. Rhea is known for its heavily cratered surface and its composition of ice and rock, making it highly reflective.
