Eponym Wilhelm von Biela

Biela is a lunar impact crater that is located in the rugged highlands of the southeastern Moon and is named after Wilhelm von Biela. The crater lies to the east of Rosenberger, to the southeast of the Watt–Steinheil double crater.

Due to foreshortening, this crater appears oval when viewed from the Earth where it can be mostly seen, the remainder can be seen through a binoculars or a telescope. From orbit, however, the crater rim is nearly circular.

The rim of this crater is overlaid by a pair of small but notable craters: Biela C across the northeast rim and Biela W along the western inner wall. The satellite crater Biela B is attached to the southwestern outer rim, and ejecta from Biela covers the northwestern part of the interior. Despite a certain degree of wear, the rim of Biela remains relatively well-defined, especially in the southeast.

The interior floor is flat and not marked by any craterlets of note. There is a central peak formation of three ridges located just to the northeast of the midpoint.

Satellite craters

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