Eponym Johann F. Encke

Encke is a lunar crater that is located on the western edge of the Mare Insularum, to the south-southeast of the crater Kepler. The small crater Kunowsky lies to the east-southeast on the mare.

The rim of Encke is low and somewhat polygonal in shape. The tiny craterlet Encke N lies across the western rim. The floor is somewhat uneven, and is covered in ray material from the nearby Kepler. The high albedo of this ejecta makes Encke a bright feature when the Sun is at a high elevation over the lunar surface.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Encke.
