Pirquet is an eroded lunar impact crater that lies to the northwest of the larger crater Levi-Civita on the far side of the Moon. About three crater diameters to the west is the prominent Tsiolkovskiy. To the north-northeast of Pirquet is Denning.

The rim and interior of Pirquet are marked by a number of small craterlets. A small crater is protruding into the inner wall along the south-southeastern side. This crater is slightly elongated along the east–west direction, making it appear slightly oval.

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 Pirquet.

Amundsen (crater) lunar impact crater

Amundsen is a large lunar impact crater located near the south pole of the Moon, named after the Norwegian explorer Roald Amundsen. It lies along the southern lunar limb, and so is viewed from the side by an observer on the Earth. To the northwest is the crater Scott, a formation of similar dimensions that is named for another Antarctic explorer. Nobile is attached to the western rim.

Cantor (crater)

Cantor is a lunar impact crater that is located on the northern hemisphere on the far side of the Moon. The outer rim of the crater has a distinctly hexagonal shape, and is slightly longer in the north–south direction. The interior walls are multiply terraced, although less so along the western rim. There is a low central peak at the midpoint of the floor.

Birt (crater)

Birt is a lunar impact crater located in the eastern half of the Mare Nubium and west of the Rupes Recta. It was named after British selenographer William R. Birt.

Ariadaeus (crater)

Ariadaeus is a small, bowl-shaped lunar impact crater on the western shores of Mare Tranquillitatis. It lies to the north of the crater Dionysius, and to the west-southwest of Arago. The crater is joined along the northeast rim by the slightly smaller Ariadaeus A, and the two form a double-crater. Its diameter is 10.4 km.

Capella (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.

Almanon (crater) Lunar crater of caliph Al-Mamun

Almanon is a lunar impact crater that lies in the rugged highlands in the south-central region of the Moon. It was named after Abbasid Caliph and astronomer Al-Ma'mun. It is located to the south-southeast of Abulfeda, and to the north-northeast of the smaller crater Geber. The crater chain designated Catena Abulfeda forms a line between the south rim of Abulfeda and the north rim of Almanon, continuing for a length of about 210 kilometers to the Rupes Altai scarp.

Burckhardt (crater) Lunar impact crater

Burckhardt is a lunar impact crater that is located in the northeast part of the Moon. It lies between the craters Geminus just to the north and Cleomedes to the south.

Armiński (crater)

Armiński is a small lunar impact crater that is located on the far side of the Moon, to the northeast of the large walled basin Gagarin. To the northwest of Armiński is the crater Beijerinck, and to the southeast lies Cyrano.

Boss (crater)

Boss is a lunar impact crater that is located along the northeast rim of the Moon's near side. Due to its location, the crater is viewed from the side by observers on the Earth, and its visibility is subject to libration effects.

Borda (crater)

Borda is a lunar impact crater that lies between Santbech to the north-northwest and Reichenbach slightly further away to the south-southeast. It was named after French astronomer Jean-Charles de Borda. It has a low rim that is broken along the southeast by a smaller crater. The rim is intruded into by another small crater along the southwest side, and there is an irregular cleft along the northwest face. There is a central peak at the midpoint of the floor.

Cysatus (crater)

Cysatus is a lunar impact crater that is located in the southern part of the Moon's near side. It is joined to the northeastern rim of the larger crater Gruemberger, and intrudes slightly into the interior of that formation. Due south is the larger Moretus, and to the east is Curtius. These craters appear foreshortened when observed from Earth because of their far south location.

Dechen (crater)

Dechen is a small, bowl-shaped crater that is located in the northwest part of the Oceanus Procellarum, near the northwest limb of the Moon. The rim of the crater projects slightly above the surrounding lunar mare, and the interior is symmetrical and nearly featureless. It lies to the northeast of the crater Harding, but is otherwise relatively isolated.

Chevallier (crater)

Chevallier is a lunar impact crater that is located in the northeastern part of the Moon's near side, about a crater diameter east-southeast of the prominent crater Atlas. To the south-southeast of Chevallier is the flooded crater Shuckburgh.

Couder (crater)

Couder is a small lunar impact crater that is located just behind the western limb of the Moon, in a region of the surface that is brought into view during favorable librations. It lies on the inner foothills of the Montes Cordillera, a ring-shaped mountain range that surrounds the Mare Orientale impact basin.

Cyrano (crater)

Cyrano is a lunar impact crater that lies on the far side of the Moon. It lies due east of the huge walled plain Gagarin, and to the north of the somewhat smaller crater Barbier.

Chaucer (crater)

Chaucer is a lunar impact crater that is located to the west of the walled plain Hertzsprung, on the far side of the Moon. It lies to the northwest of the crater Vavilov and east of the Tsander–Kibal'chich crater pair. This is a circular crater with a slightly eroded outer rim. The interior floor is nearly featureless, with only a few tiny craterlets marking the surface. It is named after the writer Geoffrey Chaucer.

Fourier (crater)

Fourier is a lunar impact crater that is located in the southwestern part of the Moon's near side, just to the southeast of the crater Vieta. To the northeast is the Mare Humorum. The rim of this crater is roughly circular, but appears oval when viewed from the Earth due to foreshortening.

Danjon (crater)

Danjon is a lunar impact crater on the far side of the Moon. It lies less than a crater diameter to the east-southeast of the larger crater Langemak. To the east-northeast of Danjon is the crater Perepelkin, and due south lies the walled plain Fermi.

Fleming (crater)

Fleming is a large lunar impact crater that is located on the Moon's far side, and cannot be seen from the Earth. It lies about a crater diameter to the east-northeast of Hertz, and to the northwest of Lobachevskiy.

Levi-Civita (crater)

Levi-Civita is a lunar impact crater formation that lies on the far side of the Moon. It was named after Italian mathematician Tullio Levi-Civita. It is located just to the southwest of the large walled plain Gagarin, and nearly as close to the crater Pavlov to the south-southwest. To the northwest of Levi-Civita lies the smaller crater Pirquet.
