Rhea and the Rings

949-mile-wide Rhea floats in front of the rings and the brightly-lit face of Saturn in this image from Cassini, taken on November 8.

The face of Saturn, overexposed here in order to see detail in the rings and Rhea, appears as bright white, making a dramatic studio backdrop. The planet’s uppermost atmospheric haze is also visible along its limb, behind which the far side of the rings disappear.

I’m not sure what the smaller moon is. Perhaps Mimas? Open to clarification. 🙂
