Rosenberger (crater)
Encyclopedia
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.
This crater is located in a region rich with prominent craters. The slightly smaller Vlacq
is nearly attached to the northwestern outer rim of Rosenberger. Other nearby craters of note include Biela
to the east, Hagecius
to the south-southeast, and Nearch
to the south-southwest. Due west past Vlacq is Hommel
.
This crater has been heavily eroded by a history of impacts, so that the outer rim has become rounded and somewhat indistinct. As a result the crater possesses only a shallow rise along the rim edge, and it nearly forms a circular depression in the surface. The satellite crater Rosenberger D, which is about 50 kilometers in diameter, intrudes into the southern rim of Rosenberger. A number of smaller, worn impact craters lie along the remainder of the rim and inner wall.
The interior floor of this crater forms a relatively level surface that is marked by several small craterlets. To the south-southeast of the mid-point is the worn remains of a small crater. At the mid-point there is a low central peak joined to a small craterlet to the north.
Moon
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...

Hagecius (crater)
Hagecius is a lunar impact crater in the southeastern part of the Moon's near side. This crater forms a triangular formation with the craters Rosenberger to the north-northwest and Nearch to the west-northwest. Like both of these craters, Hagecius has undergone erosion from subsequent impacts, and...

Hommel (crater)
Hommel is a lunar crater located in the southeast section of the Moon, in a region that is deeply impacted with a multitude of impact craters. The most notable craters nearby are Pitiscus to the north; Rosenberger due east; and Nearch to the southeast. The prominent crater Vlacq is nearly attached...
