Sasserides (Moon)

Named after Sasceride, Gellio Sasserides - Danish astronomer, doctor (1562-1612).

Sasserides is the remains of a lunar crater in the southern part. It is located less than one crater diameter to the north of the prominent crater Tycho, and west of Orontius. To the north is Ball. This formation has been so battered and ruined by impacts that it is scarcely recognizable as a crater. (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.
