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.
