Go Back

These images of Dione's orbital companion Helene were taken by Cassini on August 16, 2006 from a distance of about 50,000 kilometers. The moonlet was lit at a high phase angle so only a crescent is lit by the Sun. Both views are made from the same set of images. The one on the left shows the sunlit crescent, while the one on the right shows details on the night side visible in yellowish Saturnshine.
