This view looks toward the Trailing Hemisphere of Mimas (approx. 396 Km, or about 246 miles, across). North on Mimas is up and rotated 1° to the left.

The image was taken in Visible Green Light with the Cassini Spacecraft narrow-angle camera on Oct. 14, 2009. The view was acquired at a distance of approx. 273.000 Km (such as about 170.000 miles) from Mimas and at a Sun-Mimas-Spacecraft, or Phase, Angle of 5°.
Image scale is roughly 2 Km (about 1,4 miles) per pixel".
