Perrine Crater ( lat. Perrine ) - a large ancient impact crater in the northern hemisphere of the far side of the moon . The name was given in honor of the US-Argentine astronomer Charles Dillon Perrain (1867-1951) and approved by the International Astronomical Union in 1970. The formation of the crater dates back to the preectarian period [1] .

Crater Description
The immediate neighbors of the crater are the Quetelet crater in the west; Gulstrand Crater in the north-north-west; Wood Crater in the east-northeast; Landau Crater in the east; Charlier crater in the south-south-east and Til crater in the west-south-west [3] . Selenographic coordinates of the center of the crater , diameter 87.4 km [4] , depth 2.8 km [5] .
Perrain crater has a polygonal shape and is significantly destroyed, the western part of the bowl and shaft is blocked by the satellite Perrain S crater, which, in turn, is adjacent to the satellite crater Perrain T. The shaft is flattened, almost equal to the surrounding area in the northern and southern parts, better In total, the southeastern part of the shaft with a fairly clearly defined edge has been preserved. The eastern part of the shaft is slightly overlain by a pair of satellite craters Perrain E and G. The inner slope of the shaft in the eastern part retained the remains of a terrace-like structure. The bottom of the crater bowl between the eastern part of the rampart and the satellite Perrain S crater is crescent-shaped, relatively flat and marked only by a pair of small craters.
