Sharp is a
lunarimpact crater located to the west of the
Sinus Iridum bay of the
Mare Imbrium, beyond the
Montes Jura range. To the southwest is the crater
Mairan. Because of its location and foreshortening, Sharp appears elliptical from the earth.
Sharp is surrounded by a rugged region of mountains and rises. Ridges are joined to the north and south ends of the rim. The crater has a low central peak at the midpoint of the floor. Between Sharp and Sharp A is an unnamed sinuous
rille. The more distant
Rima Sharp is located on the
Mare Frigoris to the northwest.
