Eponym | Otto A. Rosenberger |
Rosenberger is an old lunar impact crater in the southeastern part of the Moon. It was named after German astronomer Otto August Rosenberger. [1]
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 rest 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 midpoint is the worn remains of a small crater. At the midpoint there is a low central peak joined to a small craterlet to the north.
By convention, these features are shown on lunar maps by placing the letter on the side of the crater midpoint that is closest to Rosenberger.

Anaximenes is a low-rimmed lunar impact crater near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon.
Anděl is a lunar impact crater that lies in the rugged central highlands of the Moon. It was named after the Czech astronomer Karel Anděl. Nearby craters of note include Abulfeda to the south-southeast and Descartes to the east-southeast. About 85 kilometres to the east-northeast of the outer rim is the landing site of the Apollo 16 mission.
Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.
Asclepi is a heavily eroded lunar impact crater that lies in the rugged southern highlands of the Moon. The outer rim has been worn down and rounded by many millions of years of subsequent impacts, so that it is now nearly level with the surrounding terrain. As a result, the crater is now little more than a depression in the surface. The interior is nearly flat and relatively featureless.
Babbage is an ancient lunar impact crater that is located near the northwest limb of the Moon, named after Charles Babbage. It is attached to the southeastern rim of the prominent crater Pythagoras. The crater remnant named South intrudes into the southeastern floor of Babbage.
Bergstrand is a lunar impact crater that lies on the far side of the Moon. It is located just to the southeast of the prominent crater Aitken, and northeast of the walled plain Vertregt.
Bose is a lunar impact crater that is located on the far side of the Moon, in the southern sphere hemisphere. It lies just to the northwest of the smaller crater Bhabha, and southeast of Alder.
Belʹkovich is a large lunar impact crater of the form termed a walled plain. The formation has been heavily eroded by a history of subsequent impacts, leaving it reshaped, worn, and the features softened and rounded. Belʹkovich is located along the northeastern limb of the Moon, and so its visibility is subject to libration effects. From the Earth this crater is viewed from the side, making it difficult to view it in detail.
Brianchon is a lunar impact crater that is located along the northwestern limb of the Moon. Due to its location, from the Earth the crater is seen from the edge and its visibility is somewhat affected by libration. Thus for a more detailed view, the crater must be viewed from orbit.
Biela is a lunar impact crater that is located in the rugged highlands of the southeastern Moon. It is named after Austrian astronomer Wilhelm von Biela. The crater lies to the east of Rosenberger, to the southeast of the Watt–Steinheil double crater.
Fabry is a large lunar impact crater of the form termed a walled plain. It is located on the far side of the Moon, just beyond the northeastern limb. Parts of this area are sometimes brought into view by the effects of libration, but the terrain is seen from the edge and so not much in the way of detail can be observed.
Breislak is a lunar impact crater that lies within one crater diameter north-northwest of the crater Baco, in the southern part of the Moon. To the north-northwest is the crater Barocius, and to the west lies Clairaut. This crater was named in honor of geologist Scipione Breislak.
Vlacq is a prominent lunar impact crater that is located in the southeastern part of the Moon, and appears foreshortened when viewed from the Earth. This crater is adjacent to the northeastern rim of the larger Hommel, and to the northwest rim of Rosenberger.
Hagecius is a lunar impact crater in the southeastern part of the Moon's near side. It was named after 16th century Czech naturalist Tadeáš Hájek. 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 its outer rim is worn and irregular. The southeastern rim in particular is overlaid by three smaller craters designated Hagecius C, B, and G.
Evershed is a lunar impact crater on the far side of the Moon, named after the English solar astronomer John Evershed. It is located to the northeast of the larger crater Cockcroft, and to the north of the smaller Van den Bergh.
Lebedev is a crater on the far side of the Moon. It is located at the eastern edge of the irregular feature known as Mare Australe. The crater lies to the southeast of the larger, flooded Lamb, and to the east-northeast of Anuchin. To the southeast of Lebedev lies the smaller crater Cassegrain.
Stebbins is a large lunar impact crater on the far side of the Moon. It is located along the north-northeastern rim of the even larger crater Birkhoff, with about one-third of Stebbins laid across the interior of Birkhoff. To the north of Stebbins is the smaller Hippocrates, and to the west is Sommerfeld.
Wiener is a lunar impact crater that lies on the Moon's far side. It is located just to the southwest of the larger crater Campbell. To the southwest of Wiener is the heavily worn Kurchatov. To the east along the rim of Campbell is Von Neumann. The smaller crater Pawsey lies to the north-northwest, and is partly overlain by the outer rampart of Wiener.
Prandtl is an impact crater on the far side of the Moon. It lies across the southeastern outer rim of the huge walled plain Planck.
Razumov is an impact crater on the far side of the Moon, beyond the northwestern limb as seen from the Earth. It lies along the southeastern outer rim of the walled plain Landau. Intruding slightly into the southern rim is the slightly smaller crater Petropavlovskiy. To the west-southwest lies Frost.
