Harden (Moon)

Named after Sir Arthur Harden - British chemist; Nobel laureate (1865-1940).

Harden is a small lunar impact crater that lies in the eastern part of the interior floor of the walled plain Mendeleev. It is located on the far side , and cannot been seen from the Earth. The crater is a circular, bowl-shaped feature with a slightly higher albedo than the surrounding terrain, but lacks the skirt of bright ejecta that many young impacts possess. The edge and interior are not notably eroded, and no significant craters overlie this feature. (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.
