It is located on the far side of the Moon from the Earth, to the north of the huge walled plain Apollo.

The largest of these is the satellite crater Plummer M intruding into the southern rim.

Slightly smaller is Plummer W overlapping part of the northwestern outer rim.

The interior floor of Plummer is marked by only a few tiny craterlets, and a central peak offset just to the east of the midpoint.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Plummer.
