Lebedev (crater)
Encyclopedia
Lebedev is a crater
on the far side of the Moon
. 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.
Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Mare Australe
Mare Australe is a lunar mare located in the southeastern hemisphere of the Moon. It is 603 kilometers in diameter, overlapping the near and far sides of the Moon. Smooth, dark volcanic basalt lines the bottom of the mare...

Lamb (crater)
Lamb is a lunar crater that lies beyond the southeastern limb on the Moon's far side. It is located in an irregular lunar mare region named Mare Australe, just to the east of the crater Jenner....

Anuchin (crater)
Anuchin is a lunar impact crater that lies on the southern hemisphere on the far side of the Moon. It is located to the south of the larger crater Lamb, and to the north-northwest of Kugler....

Cassegrain (crater)
Cassegrain is a lunar impact crater that is located on the far side of the Moon, beyond the southeastern limb. It lies to the southeast of the larger crater Lebedev, and to the northeast of the comparably-sized Priestley....

Lava
Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...
