Mimas and Saturn - Universe Today
This is a photograph of Saturn's icy moon Mimas, perched in front of the ringed planet. Mimas is only 397 kilometers (247 miles) across, so it's absolutely dwarfed by Saturn in the background. NASA's Cassini spacecraft took this photograph on January 20, when it was approximately 1.4 million kilometers (900,000 miles) from Mimas.
