Named after Paul Guthnick - German astronomer (1879-1947).
Guthnick is a lunar impact crater that lies on the far side 's surface from the Earth. However, it is located in the part of the far side that is sometimes brought into sight of the Earth due to libration, although it can only be seen at a low angle and during favorable lighting conditions. Guthnick is situated in the southern portion of the huge skirt of ejecta that surrounds the Mare Orientale impact basin. Less than a crater diameter to the northwest is the slightly larger crater Rydberg. (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.
