Guthnick is a
lunar impact crater that lies on the
far side of the
Moon'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
Rydberg crater. To the south-southwest is the small
Andersson crater.
The outer rim of this crater is sharp-edged and free from significant erosion. There is a small outward bulge in the rim to the northeast, but otherwise the rim is nearly circular. The loose material on the inner surface has slumped down near the floor, forming a simple sloping edge around most of the sides. The small interior floor is located in the middle of this ring of talus. The interior is free of impacts of note.
