Here’s a cool picture taken by Cassini of Saturn and one of its moons, Mimas – 397 kilometers (247 miles) across. If you look really closely, Mimas is that grey dot down near the bottom right-hand corner of the picture. Cassini took this photo on May 11, 2007 when it was approximately 720,000 kilometers (448,000 miles) from Saturn.
