Geological Chronicle

Perepelkin is an impact crater on the far side of the Moon, measuring 88.74 kilometers in diameter. Situated just south of the similar crater Love, its southern outer rim is attached to the smaller Shirakatsi. The surrounding landscape includes Lane less than one crater diameter to the east-northeast, with the conjoined craters Danjon and D'Arsonval lying to the west-southwest.

The rim of the crater is relatively heavily eroded and resembles the appearance of Love to the north. Along the western inner wall sits an odd pear-shaped crater, probably formed by two merged impacts, while a short chain of small craters lines the southwestern inner wall. The floor is pitted by tiny impacts but remains relatively level compared to the surrounding terrain, featuring a small central peak with a ridge extending southeast.

Before receiving its formal name, the crater was cataloged as Crater 285. The International Astronomical Union officially named the feature in 1970 in honor of Soviet astrophysicist Yevgeny Perepyolkin.
