Langemak is a prominent lunar impact crater on the far side of the Moon. It is located less than a crater diameter west-northwest of Danjon crater, and nearly due east of Meitner crater. To the southwest of Langemak is Kondratyuk crater. Langemak partly overlays the larger and older 'Langemak N' crater. This feature is also attached to the northeastern rim of Kondratyuk.
To the northeast of Langemak is Necho crater, an impact feature that lies at the locus of a bright ray system. Ray material from this impact lies across the rim and interior of Langemak, particularly along the northwest and eastern halves.
The outer rim of Langemak is relatively fresh and well-defined. The most notable impact along the rim is the small Sherrington crater along the southwest edge. The remainder of the rim is roughly circular, but irregular with multiple small outward bulges. The inner wall is terraced in places, with the appearance of slumping along parts of the upper edge.
Within the interior is a low, curving central ridge near the mid-point. There is a patch of lower albedo material to the southwest of this ridge, extending to the edge of the inner wall.
[edit] Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Langemak crater.
