Friedman crater ( lat. Fridman ) - a large impact crater in the equatorial region of the far side of the moon . The name was given in honor of the Russian and Soviet mathematician , physicist and geophysicist Alexander Alexandrovich Friedman (1888-1925); approved by the International Astronomical Union in 1970

Crater Description
The nearest neighbors of the crater are Evans crater in the west-north-west; the huge crater of Hertzsprung in the north; the crater of Lucretius in the northeast; the crater of Ouzo in the south-southeast and the crater of Ioffe adjacent to the south-western part of the crater. In the north of the crater there is a chain of craters of Lucretia , in the east - the East Sea [2] . The selenographic coordinates of the center of the crater are , diameter 101.5 km [3] , depth 2.9 km [4]
The Friedman crater is formed in the strata of rocks ejected during the formation of the Herzshprung crater and the basin of the Eastern Sea . It has a polygonal shape and is considerably destroyed. The shaft is flattened, in places it became equal to the surrounding terrain and marked by a multitude of small craters, the northern part of the shaft is marked by a radial chain of craters relative to the Sea of the East. The south-western part of the rampart is best preserved. The bottom of the bowl is crossed, marked by many small craters. The south-western part of the bowl is covered with rocks thrown out during the formation of the Ioffe crater.
