Schaeberle (lunar crater)
Encyclopedia
Schaeberle is an impact crater
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...

 on the far side of the Moon
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...

. It lies to the northeast of the much larger walled plain Milne
Milne (crater)
Milne is a large lunar crater that is located in the southern hemisphere on the far side of the Moon, named after the British mathematician and astrophysicist Edward Arthur Milne...

. Due north of Schaeberle is the relatively fresh crater Izsak
Izsak (crater)
Izsak is a small lunar impact crater that is located on the Moon's far side, hidden from view from the Earth. It lies about half-way between the walled plains Fermi to the northeast and Milne to the southwest. Due south of Izsak is the larger crater Schaeberle. Izsak is a circular, nearly symmetric...

, and an equal distance to the east-northeast lies Zhiritskiy
Zhiritskiy (crater)
Zhiritskiy is a lunar crater that is located on the far side of the Moon. It lies to the south of the large walled plain Fermi, and northwest of the crater Schaeberle....

.

This crater has a worn and eroded outer rim. There is a small crater attached to the outer rim along the northwest, and an irregular section at the southern end. What marks this crater as relatively unusual for a far side formation, however, is the interior floor. It has the relatively lower albedo
Albedo
Albedo , or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it...

 that is characteristic of resurfacing by flows of basalt
Basalt
Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey...

ic lava
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...

, although it is not nearly as dark as the floor of Tsiolkovskiy
Tsiolkovskiy (crater)
Tsiolkovskiy is a large lunar impact crater that is located on the far side of the Moon. It lies in the southern hemisphere, to the west of the crater Gagarin, and northwest of Milne. Just to the south is Waterman, with Neujmin to the south-southwest. This feature was discovered on photographs sent...

. The floor is marked only by a few tiny craterlets.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Schaeberle.
