Oenopides (crater)
Oenopides is a
lunar crater that is located near the northwest limb of the
Moon, and so appears foreshortened when viewed from the
Earth. This formation lies due south of the prominent
Pythagoras crater, and is attached to the southwest rim of 'Babbage E'. The southwest rim of Oenopides is part of the northern edge of
Oceanus Procellarum. To the south is the
Markov crater.
This formation is an old crater that has been heavily eroded by subsequent impacts, leaving a low outer rim that is generally hilly and contains a few clefts. There is a gap in the southeast rim, and the level interior is attached to the
lunar mare to the south. There are several small craters lying near the eastern rim, and the remainder of the floor is marked by tiny craterlets.
To the southwest is the remnant of 'Oenopides R', of which only parts of the rim are still protruding above the surface and the southern rim is completely missing.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Oenopides crater.
