Pandora Shepherding the Rings - Universe Today
In this photograph taken by Cassini, you can see the faint moon Pandora moving through Saturn's F ring. As a shepherd moon, Pandora and its partner Prometheus confine and shape the main F ring with its gravity. Pandora is 84 kilometers (52 miles) across. This image was taken on August 2, 2005, when Cassini was approximately 610,000 kilometers (379,000 miles) from Pandora.
