Polzunov is a lunar impact crater that is located just to the south-southeast of the larger crater Seyfert, on the far side of the Moon. It was named after Russian heat engineer Ivan I. Polzunov. [1] About one crater diameter to the west-southwest lies Deutsch, and somewhat farther to the south-southeast is Olcott.

Contents

This crater has a worn and eroded outer rim, although it is marked only by a few small craterlets. Along the southwestern exterior is the satellite crater Polzunov N, a relatively fresh crater with a prominent central peak. The interior of Polzunov is marked only by an uneven region near the northern end of the crater. There is no central peak to speak of, and the remainder of the floor is relatively level and marked only by 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 Polzunov.

Bartels (crater) Lunar impact crater

Bartels is a lunar impact crater located along the western perimeter of the Moon's visible face. At this location the crater is viewed from the side, and visibility is affected by libration. The crater can be viewed in its entirety only from lunar orbit. It is located to the north of the crater Moseley and south-southeast of Voskresenskiy.

Capella (crater) Lunar impact crater

Capella is a lunar impact crater 49 km (30 mi) in diameter that lies to the north of the Mare Nectaris, in a rugged region with many small impact craters. It was named after Roman astronomer Martianus Capella. It intrudes slightly into the eastern rim of the crater Isidorus, a feature only slightly smaller in diameter.

Arnold (crater) Lunar impact crater

Arnold is a lunar impact crater that is located in the north-northeastern part of the visible Moon, near the lunar limb. This location gives the crater a notably oval appearance due to foreshortening, although the formation is actually relatively round. It lies to the northeast of the Mare Frigoris, to the north of the crater Democritus. West of Arnold is the smaller crater Moigno.

Artemʹev (crater) Lunar impact crater

Artemʹev is a lunar impact crater that is located on the far side of the Moon. The rim of this crater has been modified by subsequent impacts in the vicinity, with an inward bulge along the southwest edge and a worn impact lying across the north rim. The satellite crater Artemʹev G is partly overlain by the southeast rim of Artemʹev. The crater interior is relatively flat, and marked only by tiny craterlets.

Asclepi (crater)

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 (crater)

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 Playfair.

Brianchon (crater) Lunar impact crater

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 (crater) Lunar impact crater

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.

Paneth (crater)

Paneth is a lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb. It lies just to the north-northeast of the crater Smoluchowski, and to the east-southeast of Boole on the near side.

Bellinsgauzen (crater) Lunar impact 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.

Breislak (crater) Lunar impact crater

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.

Bhabha (crater)

Bhabha is a lunar impact crater that is located in the southern part of the Moon's far side. It is nearly attached to the southeast rim of the larger crater Bose, and the outer rampart of that crater has produced a slight inward bulge along the northwest face of Bhabha. Other nearby craters of note include Stoney to the east, and Bellinsgauzen to the south.

H. G. Wells (crater) Lunar crater

H. G. Wells is a lunar impact crater that is located on the far side of the Moon, behind the northeastern limb. It lies to the south of the crater Millikan, and to the northeast of Cantor. Just to the southeast is the smaller Tesla. The crater is named after the author H. G. Wells whose works include the 1901 novel The First Men in the Moon.

Carver (crater) Lunar impact crater

Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.

Cailleux is a lunar impact crater that is attached to the southwest rim of the walled plain Poincaré. It is located in the southern part of the Moon's far side, and cannot be seen from the Earth. To the southeast of Cailleux is the crater Lyman, and nearly due westward is Prandtl.

Dale (crater)

Dale is a small lunar impact crater located in the far eastern part of the Moon's near side, to the south of the Mare Smythii. It lies to the southeast of the larger crater Kastner and northeast of Ansgarius. The crater is located in a part of the lunar surface that is subject to libration, which can hide it from view for periods of time.

Jenkins (crater) Lunar impact crater

Jenkins is a lunar impact crater that lies along the equator of the Moon, near the eastern limb. It is attached to the eastern rim of the slightly larger crater Schubert X, intruding somewhat into the interior. The crater Nobili is likewise attached to the western rim of Schubert X and intrudes slightly into the interior on that side. The three craters form a linear chain along the equator.

Rosenberger (crater)

Rosenberger is an old lunar impact crater in the southeastern part of the Moon. It was named after German astronomer Otto August Rosenberger.

Seyfert (crater)

Seyfert is a prominent lunar impact crater that is located on the far side of the Moon. It was named after American astronomer Carl Keenan Seyfert. It lies behind the eastern limb of the Moon, to the east of the crater Espin. Just to the north of Seyfert is the crater Harriot and equally close to the south is Polzunov.

Innes (crater)

Innes is a lunar impact crater on the Moon's far side. It is located less than a crater diameter to the east-southeast of the prominent crater Seyfert. To the southeast of Innes is the crater Meggers, and to the west-southwest lies Polzunov.
