New Mimas Image: Not Quite Round

CICLOPS has released this low-phase view of Saturn's moon Mimas. Due to Mimas' small size and rapid rotation, it has an oblong shape, with equatorial radii much greater than its polar radii. This trait is best seen in low-phase images such as this one. Geologically, this view shows Herschel crater at the 9 o'clock position as well as numerous craters to the east. The image has a resolution of 5 km/pixel but has been magnified by 2x to aid feature visibility. It was taken on May 20, 2005 from a distance of 916,000 km.
