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.

An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth.

Earth's Moon is an astronomical body that orbits the planet and acts as its only permanent natural satellite. It is the fifth-largest satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits. The Moon is, after Jupiter's satellite Io, the second-densest satellite in the Solar System among those whose densities are known.

Berkner is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It is attached to the east-southeast rim of the crater Parenago. Just to the south is the Robertson, and to the southeast is Helberg.

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 edge the inner wall in the southeast quadrant of the interior floor. The floor is otherwise relatively level and is marked by only a few tiny craterlets.

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 Parenago.

Abul Wafa is an impact crater located near the lunar equator on the far side of the Moon, named after the Persian mathematician and astronomer Abu al-Wafa' Buzjani. To the east are the crater pair Ctesibius and Heron. In the northeast lies the larger crater King, and to the southwest is Vesalius.

Anderson is a lunar impact crater that is located on the far side of the Moon. It is located to the northwest of the crater Sharonov, and the satellite crater Sharanov X is attached to the southeast rim of Anderson. To the northeast is the peculiar formation Buys-Ballot, and to the east-southeast lies the larger crater Spencer Jones.

Landau is a large lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It was named after physicist Lev Landau. The crater Wegener is attached to the northeastern rim. Attached to the southeastern rim is Frost.

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.

Azophi is a lunar impact crater that lies in the rugged south-central highlands of the Moon. The crater is named after the 10th-century Persian astronomer Abd Al-Rahman Al Sufi, also known by his western name, Azophi. The northwest rim is attached to the slightly smaller crater Abenezra, to the east-southeast is the large and irregular Sacrobosco, and to the west-southwest is the slightly crater Playfair.

Blanchinus is a lunar impact crater that is situated in the rugged south-central highlands of the Moon. The crater is named after Italian astronomer Giovanni Bianchini whose Latinized name is Blanchinus. Adjacent to the south of Blanchinus is the crater Werner, and La Caille is attached to the northwest rim. West of the crater is the prominent formation Purbach.

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.

Bellinsgauzen is a lunar impact crater that lies in the southern part of Moon, on the far side from the Earth. It is attached to the northern rim of the larger crater Berlage, and within a half crater diameter of Cabannes to the west. North of Bellinsgauzen is the crater Bhabha.

Barringer is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It is attached to the north-northeastern rim of the walled basin named Apollo, and lies to the southeast of Plummer. South of Barringer, on the floor of the Apollo basin, is the crater Scobee.

Boussingault is a large lunar impact crater that lies near the rugged southeast limb of the Moon. Because of its location, Boussingault appears highly oblong in shape due to foreshortening. To the southwest is the crater Boguslawsky, and almost attached to the northeast rim is Helmholtz. East-southeast of Boussingault lies the crater Neumayer.

Darwin is a lunar impact crater of the type categorised as a walled plain. It lies in the southeastern part of the Moon, and is sufficiently close to the limb to appear significantly foreshortened when viewed from the Earth. Attached to its southern rim is Lamarck. To the northeast is the dark-floored crater Crüger.

Wilhelm is a lunar impact crater in the southern part of the Moon, to the west of the prominent Tycho. Portions of the ray material from Tycho lie across the rim and floor of Wilhelm. Attached to its southern rim is the crater Montanari, while Lagalla is attached to the southwest. To the north-northeast is Heinsius.

Cajori is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies to the southwest of the walled plain Von Kármán, and to the east-southeast of the crater Chrétien.

Chandler is a lunar impact crater in the northern hemisphere, on the Moon's far side. It lies to the southeast of the large walled plain D'Alembert, and southeast of the slightly smaller Chernyshev crater.

Gauricus is a lunar impact crater that is located in the rugged southern part of the Moon's near side. It was named after Italian astronomer Luca Gaurico. Nearly attached to the western rim is the heavily eroded crater Wurzelbauer, and to the north-northwest lies Pitatus.

Wilson is a lunar impact crater that lies in the southern part of the Moon's near side, to the southwest of the large walled plain Clavius. It is nearly attached to the southeastern rim of the slightly larger crater Kircher. Almost due east lies Klaproth, another walled plain.

Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen.

Fersman is a large lunar impact crater on the Moon's far side. It lies to the east of the crater Poynting, and west-northwest of Weyl. To the south is the huge walled plain Hertzsprung.

Fridman is the remains of a lunar impact crater on the far side of the Moon. It lies due south of the huge walled plain Hertzsprung, and is attached to the northeastern rim of the crater Ioffe.

Ewen Adair Whitaker was a British-born astronomer who specialized in lunar studies. During World War II he was engaged in quality control for the lead sheathing of hollow cables strung under the English Channel as part of the "Pipe Line Under The Ocean" Project (PLUTO) to supply gasoline to Allied military vehicles in France. After the war, he obtained a position at the Royal Greenwich Observatory working on the UV spectra of stars, but became interested in lunar studies. As a sideline, Whitaker drew and published the first accurate chart of the South Polar area of the Moon in 1954, and served as director of the Lunar Section of the British Astronomical Association.
