Sharp Focus on Mimas
This amazing perspective view captures battered Mimas against the hazy limb of Saturn. It is obvious in such close-up images that Mimas (397 kilometers, or 247 miles across) has been badly scarred by impacts over the eons. Its 130 kilometer- (80 mile-) wide crater, Herschel, lies in the darkness at right.
North on Mimas is up and rotated 19 degrees to the right.
The image was taken with the Cassini spacecraft narrow-angle camera on March 21, 2006 using a filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The image was acquired at a distance of approximately 191,000 kilometers (119,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 91 degrees. Image scale is 1 kilometer (3,730 feet) per pixel.
