Williams is the remnant of a lunar impact crater that lies to the south of the prominent crater Hercules, in the northeastern part of the Moon. The southern rim borders the Lacus Somniorum, a small lunar mare that extends to the south and west. To the southwest is the sharp-rimmed crater Grove.
Little remains of the original crater, besides a low curving ridge. The rim has been nearly destroyed along the northwest face, leaving only a few ridges in the surface. The remainder forms an irregular horseshoe, with the western part attached to a series of ridges leading to the west. The interior floor has been resurfaced by basaltic lava, forming a flat, nearly featureless surface that is marked only by a pair of tiny craters near the northeast rim.
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 Williams.
