Plummer is a lunar impact crater. It is located on the far side of the Moon from the Earth,[2] to the north of the huge walled plain called Apollo. Less than one crater diameter to the north of Plummer is the similar-sized Wilsing.
On the lunar geologic timescale, Plummer dates to the Nectarian period.[1] This is a worn crater formation with several notable impacts along the rim. 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. There is also a relatively fresh crater cutting across the eastern 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.
Satellite craters
[edit]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.
