Aratus, Conon and Galen
Aratus is a small lunar impact crater located on the highland to the south and east of the rugged Montes Apenninus range. It is a circular, cup-shaped crater formation with a relatively high albedo. To the east is the Mare Serenitatis, and to the southwest is the somewhat larger Conon crater. North-northeast of Aratus crater is the landing site of the Apollo 15 mission, just beyond Mons Hadley Delta.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Aratus crater.
The following craters have been renamed by the IAU.
