Helmholtz (lunar crater)

Helmholtz is a lunar impact crater that is located near the south-southeast limb of the Moon. Attached to the south-southeast rim of Helmholtz is the somewhat smaller crater Neumayer. The larger crater Boussingault is nearly attached to the west-southwestern rim.

The outer rim of Helmholtz is worn and rounded, although not significantly disrupted. The edge of the rim can still be discerned around the perimeter, although several small craters lie along the inner edge. One such crater lies across the inner southeast wall, and a pair occupies the opposite inner wall to the northeast. There are also a couple of smaller craterlets just inside the north rim.

The northern half of the interior floor is level and marked only by a few very tiny craterlets. The southern floor is more irregular due to the overlaying ejecta from Neumayer and Boussingault, and is marked by a pair of tiny craters in the southeast. There is no central peak.
