Eponym | Pyotr N. Lebedev |
Lebedev is a crater on the far side of the Moon. It is named after Russian Physicist Pyotr Lebedev. It is located at the eastern edge of the irregular feature known as Mare Australe. The crater lies to the southeast of the larger, flooded Lamb, and to the east-northeast of Anuchin. To the southeast of Lebedev lies the smaller crater Cassegrain.
This is a worn and eroded crater formation with an uneven outer rim, although no significant impacts overlay the rim edge. There are a few small craterlets along the inner wall, with a pair along the southeast and another to the southwest. The most distinctive feature about this crater, however, is the dark, lava-flooded interior. This surface is pitted with many tiny craterlets and has a low ridge in the southern half, but is otherwise level and nearly featureless.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Lebedev.

Nasmyth is a lunar impact crater located near the southwestern limb of the Moon. It is attached to the southeast rim of the flooded crater Wargentin, and the southern half is overlain by the larger Phocylides.
Flammarion is a lunar impact crater on the south edge of Sinus Medii. Its diameter is 76 km. It is named after the French astronomer Camille Flammarion. It is located between the crater Mösting to the northwest and Herschel to the southeast. The bowl-shaped Mösting A intersects the western rim of Flammarion.
Agatharchides is a lunar impact crater located at the southern edge of Oceanus Procellarum, in the region between the Mare Humorum and Mare Nubium. To the east-southeast is the crater Bullialdus, and to the south-southwest lies Loewy. It is named after the Greek geographer Agatharchides.
Alekhin is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies to the north of the crater Zeeman, and south-southeast of Fizeau. To the west lies Crommelin, and east-southeast is Doerfel.
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.
Bose is a lunar impact crater that is located on the far side of the Moon, in the southern sphere hemisphere. It lies just to the northwest of the smaller crater Bhabha, and southeast of Alder.
Chamberlin is a lunar impact crater that is located on the far side of the Moon, just past the southeastern limb. It lies to the southeast of the crater Jeans, and Moulton is attached to the southeastern rim of Chamberlin. This crater is located in a part of the lunar surface that has undergone resurfacing of crater interiors, producing dark-hued crater floors.
Olivier is an old, eroded crater that is located in the northern hemisphere on the far side of the Moon. It lies in a region of dense cratering on all sides. To the east-southeast is a younger but comparably sized crater named Störmer. Southwest of Olivier is the crater Volterra.
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.
Belopolʹskiy is a lunar impact crater that is located on the far side of the Moon. It lies to the west of the crater Houzeau, and northeast of Strömgren. Just to the northwest of Belopolʹskiy is the crater Ioffe.
Loewy is a small lunar impact crater that lies along the eastern rim of Mare Humorum, in the southwest part of the Moon's near side. It was named after French astronomer Maurice Loewy. This is a lava-flooded formation that lies to the southwest of the larger, lava-flooded crater Agatharchides. To the southeast is an even larger lava-flooded formation, Hippalus.
Helmholtz is a lunar impact crater, approximately 110 kilometers in diameter, that is located near the south-southeast limb of the Moon. Attached to the south-southeast rim of Helmholtz is the somewhat smaller crater Neumayer. The larger crater Boussingault is nearly attached to the west-southwestern rim. The crater is named after German physicist and physician Hermann von Helmholtz
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.
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.
Gum is a lunar impact crater that is located near the southeastern limb of the Moon, and is viewed nearly from the side from Earth. It lies along the western edge of the irregular Mare Australe, to the northeast of the crater Hamilton. To the north-northwest is the larger Abel, and to the east-southeast on the far side of the Moon is Jenner.
Van der Waals is a lunar impact crater on the far side of the Moon. It is a heavily eroded feature with an irregular outer rim. The edge is lowest along the southern side where it is little more than a circular crest along the ground. It is more developed along the northern side, but the rim is notched and rugged. The satellite crater Van der Waals W is attached to the exterior of the northeast, and Van der Waals H intrudes into the rim along the southeast. The interior floor is relatively even and featureless, with only a few tiny craterlets to mark the surface.
Eijkman is a lunar impact crater that is located on the far side of the Moon's southern hemisphere. It lies about a half crater diameter to the southeast of the larger crater Lemaître. To the south-southwest is the crater Crommelin, and to the northeast is Fizeau.
Minkowski is a crater on the far side of the Moon, in the lower latitudes of the southern hemisphere. The lunar crater lies about one crater diameter to the north-northeast of crater Lemaître, a formation of similar dimension. To the northwest of Minkowski is the flooded crater Baldet, and to the southeast lies Fizeau.
Pogson is a lunar impact crater on the Moon's far side, behind the southeastern limb. It is located midway between the flooded crater Lebedev to the southwest and Bjerknes to the northeast. Farther west of Pogson is the uneven Mare Australe.
Von der Pahlen is an eroded lunar impact crater that lies on the far side of the Moon from the Earth. It is located about one crater diameter to the south-southwest of the crater Strömgren. Farther to the south is the larger Chebyshev, and to the west-southwest lies Das.
