Brashear (lunar crater)
Brashear is a lunar impact crater on the far side of the Moon, in the southern hemisphere in the vicinity of the south pole. The crater is named after the American astronomer John A. Brashear.[1] It lies just to the south of the walled plain Antoniadi, within the larger crater's outer rampart of ejecta. To the northeast besides Antoniadi is the crater Numerov, and southeast lies the younger De Forest.

This formation is little more than a shallow depression in the lunar surface, its features eroded and blanketed by the ejecta from the relatively fresh crater Antoniadi just to the north.
The satellite crater Brashear P lies to the south-southwest. This formation is a heavily worn crater with features that have been almost completely worn away by subsequent impacts. Connected to the southern rim of this crater is a series of valleys and impact craters leading a couple of hundred kilometres to the east.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Brashear.
