Kirchhoff is a small lunar impact crater that is located in the northern part of the Montes Taurus range. It lies to the west of the crater Newcomb, and southeast of the crater pair of Hall and G. Bond. This is a circular, bowl-shaped feature that lies in the midst of rugged lunar terrain. The satellite crater Kirchhoff C adjoins the eastern 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.
