Kolhorster is a 97 km lunar Far Side crater located in the midsection of Ridge Section 114.  Just southwest of this crater lies the crater Michelson (Section 125), which can been seen at the bottom left. North of Kolhorster is the crater Kamerlingh Onnes, and further to the NW is Weyl.  To the south of Kolhorster is an area marked with crater chains formed from secondary impacts during the creation of the Mare Imbrium impact basin. About one crater-diameter to the southeast is the Catena Leuschner crater chain, while further to the south is Catena Michelson. The rim of Kolhorster is marked in several locations by smaller impacts that lie along or across the side. Only the west-northwestern part is relatively free from impacts. The northeastern rim is somewhat indented into the interior of the crater. Within the interior the floor is relatively featureless and level, with only a few tiny craterlets to mark the surface.
