Banachiewicz (Moon)

Named after Tadeusz Banachiewicz - Polish astronomer, mathematician (1882-1954).

Banachiewicz is a largely degraded lunar crater that is located near the eastern limb. Portions of the western and southwest rim still survive as low ridges in the surface, while the remainder is a jumble of irregular terrain with little definition. There are two small impact craters of note within the interior: Banachiewicz B is adjacent to the western rim, while the smaller Knox-Shaw is located closer to the midpoint. Just to the northeast of this formation is the large walled plain Neper, which lies on the southern edge of Mare Marginis. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
