saturn's rings would not be prominent from most of the moons. this is because the rings, though wide, are not very thick. the rings are edge-on and practically invisible from the inner moons. from the outer moons, starting with iapetus, a more oblique view of the rings would be available, although the greater distance would make saturn appear smaller in the sky; from phoebe, the largest of saturn's irregular moons, saturn would appear only as big as the full moon does from earth. the best view of the rings may be from the inner moon mimas, which is fairly near the rings. the co-orbitals epimetheus and janus would also get a good view. tethys gets the next best view; iapetus gets a good view of the rings and is more than any of the outer moons can claim.
