Resnik (crater)
Encyclopedia
Resnik is a small lunar
crater
that is located within the interior of the huge walled plain Apollo
, on the Moon
's far side. Apollo is a double-ringed formation with a central floor that has been flooded with basalt
ic lava
. Resnik is located at the northern edge of the dark area of the surface. It lies to the southwest of the smaller crater McAuliffe
.
This is a roughly circular, bowl-shaped crater. Overlying the northwestern rim is a smaller, cup-shaped impact crater with a higher albedo
than Resnik. A small, partly submerged crater is attached to the exterior along the southern rim, and a portion of a submerged crater rim lies just to the east of this feature along the same rim.
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...

Apollo (crater)
Apollo is an enormous impact crater located in the southern hemisphere on the far side of the Moon. This formation dwarfs the large crater Oppenheimer that is located next to the western rim. The crater Barringer lies across the northern wall...

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...

McAuliffe (crater)
McAuliffe is a small lunar impact crater that is located on the Moon's far side. It lies within the inner ring of the double-ringed walled plain Apollo, about one crater diameter to the northeast of the crater Resnik. To the southeast of McAuliffe lies the crater pair of Jarvis and McNair.McAuliffe...

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...
