Nicholson (Moon)

Named after Seth Barnes Nicholson - American astronomer (1891-1963).

Nicholson is a crater on Mars centered at 0.1° N and 164.5° W. It is 62 miles wide and located in the Memnonia quadrangle. Nicholson is notable for its central peak, which rises in a high mound 3.5 km above the crater floor. This rounded peak is riddled with channels, which may have been eroded by wind or even water.

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.
