Maunder is a lunar impact crater that is located on the far side of the Moon, just beyond the western limb.

To the southeast is the crater Kopff, and due south is the small Hohmann.

The rim of Maunder is roughly circular, with a sharp edge that has not been significantly eroded.

Surrounding the crater is a rough outer rampart that mixes with the rugged terrain along the northern half of the rim.

[3] By convention, these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Maunder.
