Eponym | Robert Luther |
Luther is a small lunar impact crater on the northwest part of Mare Serenitatis, at the inlet to Lacus Somniorum. To the east-southeast is the large crater Posidonius. Luther has a circular rim and is cup-shaped, with no appreciable wear from impact erosion. It lies across a wrinkle ridge on the lunar mare.
The crater is named after German astronomer Robert Luther.[1]
