Einthoven (Moon)

Named after Willem Einthoven - Dutch physiologist; Nobel laureate (1860-1927).

Einthoven is a lunar impact crater on the far side. It is located beyond the region of the surface that is sometimes brought into view due to libration, and so can not be viewed from the Earth. Einthoven is located to the northeast of the huge walled plain Pasteur. This is a circular crater with some minor terrace structure along the inner rim. (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.
