Geological Chronicle
Finsch is a relatively small lunar impact crater in the mid-part of Mare Serenitatis that has been almost completely (other than the crest of the rim) covered by the mare, forming a ghost crater in the lava plain. The formation spans an official diameter of 4.05 kilometers.
It was named after German zoologist Otto Finsch. It is recorded in the IAU Gazetteer under quadrangle LAC-42.
