The Arnold Crater ( Latin Arnold ) is an ancient impact crater in the north-northeast part of the visible side of the moon . The name was given in honor of the German astronomer Christoph Arnold (1650–1695) and approved by the International Astronomical Union in 1935. The formation of the crater belongs to the pre-sectarian period [1] .

Crater Description
The crater lies northwest of the Sea of Cold . The crater Neyson is located in the north-north-west of the crater, Meton crater in the north, Bayo crater in the north-east, Schwabe and Strabo craters in the south, Democritus crater in the south, and Muanyo crater in the west [2] . The selenographic coordinates of the center of the crater are , diameter - 93 km [3] , depth - 0.95 km [4] .
During its existence, the crater shaft was subjected to severe destruction and multiple impacts . The most preserved northern and northeastern parts of the shaft. In the southwestern part there is a passage marked by a small satellite crater Arnold J (see below). The eastern part of the shaft is significantly lower than the other parts. The greatest height of the shaft above the surrounding terrain is 1450 m [5] . The bottom of the crater is flooded with lava , the central peak is absent, most likely covered by lava. The bottom is relatively flat, dotted with many small craters, the largest of which is satellite crater Arnold F. The volume of the crater is approximately 8,600 km³ [5] .
Because of its high latitude location, the crater appears oval when observed.
