Earth's Moon
Apollo 16 metric camera picture of Ptolemaeus crater on the Moon. Ptolemaeus is 164 km in diameter and is centered at 9.3 S, 1.9 W. The interior of the crater is covered by the Cayley formation, a light-colored unit characterized by the gentle ridges and depressions, and numerous small craters. The Cayley formation may be related to the nearby Fra Mauro formation. The picture was taken from 112 km and north is up. (Apollo 16, AS16-0989)
