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 by the slightly smaller Perrine S, so that Perrine is crescent-shaped. The western rim of Perrine S is overlain by the still-smaller Perrine T. Perrine S has a worn outer rim, and a small central peak in the middle of the floor.
The surviving rim of Perrine is worn and eroded, with the overlapping pair Perrine E and Perrine G intruding slightly into the eastern rim. A smaller crater has disrupted the southwest end of the outer rim, and a pair of small craters are attached to the northern rim.
Only a small portion of the interior floor of Perrine still survives, forming a crescent-shaped surface between the outer rampart of Perrine S and the inner wall of Perrine. It is marked by a pair of tiny craterlets in the northern half.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Perrine.

Maurolycus is one of the more prominent lunar impact craters in the southern highland region of the Moon that is covered in overlapping crater impacts. It was named after 16th century Italian mathematician Francesco Maurolico. It is joined at the southeast rim by the smaller crater Barocius. Due west lie the overlapping pair of Stöfler and Faraday. To the northeast is the faint crater Buch, and further to the north lies Gemma Frisius.
Orontius is a lunar impact crater that lies in the heavily cratered southern highlands of the Moon's near side. It was named after 16th century French mathematician Oronce Fine. It is located to the northwest of the prominent ray crater Tycho, and south and east of the large walled plain Deslandres. The eastern part of the crater is overlain by the smaller crater Huggins, which is overlain in turn on its eastern rim by the still smaller Nasireddin, the trio forming a crater chain of diminishing dimensions. Joined to the southern rim is the crater Saussure. To the southwest, just east of Tycho, is Pictet.
Rowland is a large lunar impact crater that is located in the northern part of the Moon, on the far side from the Earth. This is an old, worn formation that is overlain by a number of smaller craters. The most notable of these is Rowland Y, which is attached to the inner wall along the north-northwestern rim. Additional smaller craters are attached to the inner wall along the southeastern and south-southwestern rims, the latter being designated Rowland N. Rowland C forms a double crater with a smaller, bowl-shaped formation in the eastern part of the floor.
Watt is a lunar impact crater that is located in the southeastern part of the Moon. It was named after Scottish inventor James Watt. The northwestern third of the crater rim has been completely overlain by the same-sized Steinheil, leaving much of the interior floor covered with the outer rampart of ejecta from the latter formation. The remainder of the rim of Watt is somewhat jagged in appearance, with an inward bulge along the southeast rim and a pair of small outward projections to the northeast. The rim is otherwise relatively sharply defined, with only a minor amount of wear.
Moore is an impact crater that is located on the far side of the Moon. Like much of the far side, Moore is located in a region that has been saturated by impacts. Nearby craters of note are Larmor to the south-southwest, and Parsons about the same distance to the west.
Harkhebi is a large lunar impact crater of the category termed a walled plain, on the far side. Half of the crater to the north-northeast is overlain by the walled plain Fabry, a large formation in its own right. Attached to the northwestern rim is the much smaller crater Vashakidze. To the southwest lies Vestine, and to the south is Richardson.
Poczobutt is a large lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb in an area occasionally brought into sight due to libration effects. This is a damaged formation that is partly overlain by several named craters. Across the rim to the north-northeast is the crater Smoluchowski. The crater Zsigmondy overlies the northeastern rim, and Omar Khayyam is located in the western part of Poczobutt's interior.
Vega is an eroded lunar impact crater that is located in the southeastern part of the Moon. It lies on the near side and so can be viewed from the Earth. Less than one crater diameter to the east-southeast is the slightly smaller Peirescius. About one and a half crater diameters to the west is the long Vallis Rheita.
Kulik is a lunar impact crater that lies on the northern hemisphere of the Moon's far side. The outer rim of this crater has been heavily impacted, particularly along the northern side which is almost entirely overlain by a pair of smaller craters. The southern inner wall is also marked by a cluster of small impacts, and there are small craters across the western rim and notching the eastern inner wall. The interior floor is nearly featureless, but a small central peak rises near the midpoint.
Idel'son is a lunar impact crater that is located on the far side of the Moon. It lies just behind the southern lunar limb, in a region that is sometimes brought into view of the Earth due to libration. Idel'son is situated to the southwest of the huge walled plain Schrödinger.
Minnaert is a large lunar impact crater that is located on the far side of the Moon, deep in the southern hemisphere. It is partly overlain along the southeastern side by the larger and younger crater Antoniadi. To the west-northwest lies Lyman.
Mach is a large lunar impact crater of the class known as a walled plain. It is located on the far side of the Moon and cannot be viewed directly from the Earth. Nearby craters of note include Joule to the northeast, Mitra attached to the western outer rim, and Henyey to the southwest.
Rynin is a lunar impact crater that is located just behind the northwestern limb, on the far side of the Moon. It is located just to the east of the larger crater Stefan, and to the southwest of Chapman.
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.
Lodygin is a lunar impact crater to the southeast of the much larger crater Galois. To the east-northeast is the crater Paschen, and to the south-southwest is the immense Apollo.
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.
Schlesinger is a lunar impact crater on the far side of the Moon. The crater Esnault-Pelterie overlies the western part of the rim and the outer rampart of that crater has covered about half the interior floor, leaving a crescent-shaped feature. To the south-southwest of Schlesinger is the crater Von Zeipel and to the southeast lies Quetelet.
Montgolfier is a worn lunar impact crater that is located in the northern hemisphere of the Moon's far side. To the east-northeast is the crater Paraskevopoulos, and southwest of Montgolfier lies Schneller. Due south is the smaller Woltjer.
Seidel is a worn lunar impact crater that lies to the east-northeast of the much larger crater Jules Verne. Farther to the east of Seidel is the western edge of Mare Ingenii, and to the northeast lies the crater O'Day.
Tsander is a large lunar impact crater on the far side of the Moon. Attached to the southeastern outer rim is the younger crater Kibal'chich. To the northwest lies Dirichlet, and to the northeast lies Artem'ev.
