Popov 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...

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...

Earth

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets...

Libration

In astronomy, libration is an oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth, or of Trojan asteroids relative to planets.-Lunar libration:...

 and illumination. However even at such times it is not prominent and can only be viewed edge-on.

This crater lies due south of Dziewulski

Dziewulski (crater)

Dziewulski is a lunar crater on the far side of the Moon. It lies between the craters Edison to the north and Popov to the south. The outer rim of this crater has been considerably worn by impacts, particularly along the southwest quadrant where the satellite crater Dziewulski Q overlies the rim...

, and the crater chain designated Catena Dziewulski passes just to the northeast of Popov's outer rim. Just to the southeast of Popov lies Möbius

Möbius (crater)

Möbius is a lunar crater that is located on the Moon's far side, beyond the eastern limb and northeast of the Mare Marginis. It lies less than one crater diameter to the northwest of the larger, 90-km-diameter Hertz, and just to the southeast of Popov...

, and the two are joined together by a smaller crater that lies along the south-southeast rim of Popov. To the southwest lies the crater Ginzel

Ginzel (crater)

Ginzel is a lunar crater that is located on the far side of the Moon, just beyond the eastern limb. It is named after the Austrian astronomer Friedrich Karl Ginzel. It lies at the eastern edge of the Mare Marginis, in a region of the surface that is sometimes brought into sight of the Earth due to...

 and Mare Marginis

Mare Marginis

Mare Marginis is a lunar mare that lies on the very edge of the lunar nearside. The selenographic coordinates of this feature are 13.3° N, 86.1° E, and the diameter is 420 km. The name is Latin for "Sea of the Edge"....

.

This is a worn crater with a damaged outer rim that is little more than a circular, jumbled series of ridges in the surface. Several small craterlets lie along the rim and inner wall, particularly along the western side. The interior floor is otherwise relatively level and nearly without any features.

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 Popov.
