SUMMARY: Two of Saturn's moons, Rhea and Dione posed for Cassini in this photograph. The lower moon is Dione, which has been much more geologically active in the past than Rhea. Dione has a smoother surface and linear depressions, while Rhea looks quite pummeled by impacts, like our own Moon. When Cassini took this image, Rhea was 1.8 million kilometers (1.1 million miles) away, and Dione was 1.2 million kilometers (800,000 miles) away.

I do love these photos. The dreamer in me can stare at them again and again.
