Biela (crater)
Encyclopedia
Biela is a lunar
impact crater
that is located in the rugged highlands of the southeastern Moon
. The crater lies to the east of Rosenberger
, to the southeast of the Watt
–Steinheil
double crater.
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 mid-point.

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Rosenberger (crater)
Rosenberger is an old lunar impact crater in the southeastern part of the Moon. Due to foreshortening, this crater appears oval when viewed from the Earth. From orbit, however, the crater rim is nearly circular....

Watt (crater)
Watt is a lunar crater that is located in the southeastern part of the Moon. The northwestern third of the crater rim has been completely overlain by the same-sized Steinheil, leaving much of the interior floor covered with the outer rampart of ejecta from the latter formation...

Steinheil (crater)
Steinheil is a lunar impact crater that is located in the rugged highlands in the southeastern part of the Moon. It forms a prominent crater pair with the similar-sized Watt, which it partly overlies to the southeast. To the northwest is the large walled plain Janssen. Due to the location of this...
