Paraskevopoulos is an old lunar impact crater that is located on the far side of the Moon, in the higher northern latitudes. It lies just to the southwest of the younger and somewhat larger crater Carnot. To the southwest is the smaller crater Stoletov, and to the southeast lies Fowler. It is named after the astronomer John S. Paraskevopoulos. This is a well-eroded crater formation, with
Parenago is an impact crater on the Moon’s far side, behind the eastern limb. Nearly attached to the east-southeastern outer rim of Parengo is the crater Berkner. To the south-southwest lies Comrie. This is a worn and eroded crater formation. Attached to the northern outer rim are the satellite craters Parenago W and Parenago Z. Three small craters lie prominently along the
Patsaev is a lunar impact crater that lies on the far side of the Moon, to the northeast of the prominent crater Tsiolkovskiy. To the northwest is the smaller crater Lander. This is a heavily damaged crater that now appears as little more than an irregular depression in the surface. Both the outer rim and interior floor are streaked by jumbled ridges of material
Perrine is a lunar impact crater that is located on the northern hemisphere on the far side of the Moon. It lies to the west of the large walled plain Landau, and to the northeast of the crater Charlier. To the north-northwest is the smaller Gullstrand. This is an unusual formation that forms part of a chain of connected craters. The western two-thirds of Perrine is overlain
Ohm is a lunar impact crater that is located on the far side of the Moon. It lies to the south of the crater Comrie, and the satellite crater Comrie K is attached to Ohm’s northeastern rim. To the northwest is the larger Shternberg, and to the southwest is Kamerlingh Onnes. This crater is located at the origin of an extensive ray system that extends for several
Oppenheimer is a large lunar impact crater that lies on the Far side of the Moon. It lies along the western outer rampart of the immense walled plain Apollo. Nearby features of note include the dark-floored crater Maksutov to the southwest, and Davisson to the west-southwest. The latter intrudes into the eastern rim of Leibnitz, a feature about 20% larger than Oppenheimer. The outer rim of Oppenheimer is
Oresme is a crater on the Moon’s far side. It lies just to the west-northwest of the larger Von Kármán. To the southwest of Oresme is Chrétien, and to the northwest is the Mare Ingenii. This crater was believed to have formed during the Nectarian epoch, about 4 billion years ago. This crater has a considerably damaged outer rim that forms an uneven, irregular
Nishina is the remnant of a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies to the south-southwest of the crater Maksutov, to the southeast of Finsen and Leibniz. The rim of this formation has been eroded, worn down, and reshaped by a history of impacts, leaving an irregular, indented perimeter surrounding the crater floor. The interior of
Nicholson is a lunar impact crater located at the western limb. In this position it is subject to libration, which can limit observation. The crater is also viewed at a very oblique angle, so it is seen from the side when observed from the Earth. It is an irregular, somewhat pear-shaped formation that has an uneven rim due to its location
Mare Moscoviense (Latin for ‘Sea of Moscow’; /ˌmɒskəviˈɛnsi/ MOSK-ə-vee-EN-see) is a lunar mare that sits in the Moscoviense basin. It is one of the very few maria on the far side of the Moon. Like Mare Marginis, this mare appears to be fairly thin. However, it is clearly centered within a large impact basin. It is also much lower than either the outer basin
