The illumination from "below" is Saturn-shine (possibly ring shine...). The illuminator to the right is Tethys with some light from Dione (both are pretty much in the same direction). The illuminator to the lower left is Rhea.

The illumination from "below" is Saturn-shine (possibly ring shine...). This would have to be a sort of ring-saturn-shine if that's what you meant, doubly reflected and dim light off of the cloud tops. Enceladus is in such a low inclination orbit, 0.019 deg (compared to Mimas' 1.51 deg) that the main rings are effectively invisible. I wonder how much light the broader F ring would diffuse and if it would be comparable in brightness to the light flux from the night side? -------------------- |
