Leibnitz in Ridge Section 152 is a huge, 245 km, impact crater located in the southern hemisphere on the lunar Far Side. It is located to the east-southeast of Mare Ingenii, and is joined to the northeast rim of Von Karman. Attached to the eastern rim of Leibnitz is Davisson (not labeled here) and intruding into the southeast rim is Finsen. Farther to the west is the large Oppenheimer (Section 153). The outer rim of Leibnitz is roughly circular, with a prominent outward bulge along the southern face. It has received some impact erosion and wear, with several tiny craters lying along the edge and the inner wall. The rim to the east and southeast has been somewhat modified by the craters Davisson and Finsen. Much of the interior floor of this walled plain has been resurfaced by lava, leaving a level, nearly featureless surface with the same low albedo as the dark lunar mare to the northwest. However the southeastern part of the floor is more irregular, and the albedo matches the surrounding terrain. The dark floor is covered in places by streaks of ray material, and several tiny craterlets. The small crater Leibnitz X near the northwest inner wall has been flooded by lava, leaving only a roughly circular rim projecting above the surface.
