Eponym	Heinrich W. M. Olbers

Olbers is a lunar crater that lies at the west edge of the Oceanus Procellarum, near the western limb of the Moon. It lies to the northwest of Hevelius crater, and to the north of the indistinct Hedin crater formation. Further to the south is the Riccioli crater. Due to its location, this crater appears very oblong because of foreshortening. It is viewed nearly from the edge, making observation of the interior difficult from the Earth.

The rim of Olbers is somewhat worn, with notches to the north, east, and south. The interior floor is relatively flat, especially toward the eastern rim, and is not marked by notable craterlets. The floor is covered by ray material and ejecta from the adjacent Glushko crater.

Satellite craters

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 Olbers crater.
