Past Night

Saturn’s moon Mimas peeks out from behind the night side of the larger moon Dione in this Cassini image captured during the spacecraft’s Dec. 12, 2011, flyby of Dione. Dione is 1123 km across and its day side dominates the view on the right of the image. Smaller Mimas is on the left and measures 396 km across. The image was taken in visible light with the Cassini spacecraft narrow-angle camera from a distance of approximately 94,000 km from Dione.
