Herschel Crater on Mimas

Caption NASA:"The great basin that interrupts the contours of this moon's crescent identifies the satellite unmistakably as Mimas. The giant crater Herschel (about 130 Km, or 80 miles wide) is this moon's most obvious feature.
North on Mimas (approx. 397 Km, or 247 miles, across) is up and rotated 23° to the left.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 8, 2006 at a distance of approx. 534.000 Km (about 331.000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 115°. Image scale is roughly 3 Km (about 1,9 miles) per pixel".
