Herschel Crater on Mimas


Herschel Crater features prominently on the moon Mimas in this Cassini spacecraft image, which gives the impression of an eye staring out into space.

Herschel Crater is about 130 kilometers, or 81 miles, wide and covers a significant part of the moon. This view looks toward the leading hemisphere of Mimas (396 kilometers, or 246 miles across). North on Mimas is up and rotated 1 degree to the right.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 3, 2010. The view was acquired at a distance of approximately 476,000 kilometers (296,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 56 degrees. Image scale is 3 kilometers (2 miles) per pixel.
