The oblate shape of Mimas is presented in this Cassini spacecraft image — the moon appears flattened at the poles with an equatorial bulge.

This view looks toward the leading hemisphere of Mimas (396 kilometers, or 246 miles across). North on Mimas is up and rotated 44 degree to the left. The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on June 25, 2009. The view was acquired at a distance of approximately 594,000 kilometers (369,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 11 degrees. Image scale is 4 kilometers (2 miles) per pixel. (Credit: NASA/JPL/Space Science Institute)
