Koval'skiy is a 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 about one crater diameter to the southeast of the prominent Sklodowska

Sklodowska (lunar crater)

Sklodowska is a large lunar impact crater that is located on the far side of the Moon. It lies just past the southeastern limb, and can sometimes be viewed from Earth under favorable conditions of libration and illumination...

, and to the north-northwest of Bowditch

Bowditch (crater)

Bowditch is a lunar crater that lies on the far side of the Moon, just beyond the eastern limb. It is located on a region of the lunar surface that is brought into view due to libration, but at such times the area is viewed from the edge and so not much detail can be observed...

 and Lacus Solitudinis

Lacus Solitudinis

Lacus Solitudinis is a small lunar mare on the far side of the Moon. The selenographic coordinates of the lake are 27.8° S, 104.3° E, and it lies within a diameter of 139 km. It forms an arcing feature with the concave side oriented to the northwest...

, a small lunar mare

Lunar mare

The lunar maria are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich compositions, and...

.

This feature has been heavily damaged by overlapping impacts, leaving it scarcely distinguishable from the irregular lunar terrain. The satellite crater Koval'skiy P lies across the southwestern rim, and Koval'skiy B intrudes into the northeastern rim. A small crater also lies across the northwestern rim. The interior is irregular and marked by several small craterlets.

Koval'skiy K lies at the mid-point of a high-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...

 patch. A single faint ray

Ray system

A ray system comprises radial streaks of fine ejecta thrown out during the formation of an impact crater, looking a bit like many thin spokes coming from the hub of a wheel. The rays can extend for lengths up to several times the diameter of their originating crater, and are often accompanied by...

extends to the southeast directly across Koval'sky.

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 Koval'skiy.
