Luther (crater)

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 Posidonius crater. This crater 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 Karl Theodor Robert Luther.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Luther crater.
