Schjellerup (Moon)

Named after Hans Carl Schjellerup - Danish astronomer (1827-1887).

Schjellerup is a lunar impact crater that is located in the far northern latitudes. This crater lies to the southwest of the larger Karpinskiy, and to the northeast of Gamow. To the northwest is the crater Seares and to the south-southeast lies Avogadro. This is a reasonably well-preserved crater that has undergone only a marginal degree of wear from subsequent impacts.

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.
