Pogson (crater)
Encyclopedia
Pogson is a lunar
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
.
This is a circular crater with a somewhat worn rim. A small craterlet lies across the southern rim, and pair is located long the northeastern rim. The interior floor has a slightly lower albedo
than the surroundings, and is level and nearly featureless.
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...

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...

Lebedev (crater)
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...

Bjerknes (lunar crater)
Bjerknes is a lunar impact crater that is located in the southern hemisphere on the rugged far side of the Moon. The crater lies behind the southeastern limb, and beyond the region that is sometimes brought into sight through libration. Thus this crater can not be viewed from Earth, and has only...

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...
