Lander is a lunar
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...

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...

Attached to the northeastern rim of Lander is Volkov J, which is joined with Volkov
Volkov (crater)
Volkov is a lunar crater on the Moon's far side. It is located to the north of the prominent crater Tsiolkovskiy, and east-southeast of Dobrovol'skiy. Overlying the southeastern rim of Volkov is the satellite crater Volkov J, and the two have merged to form a figure-8 shape...

Patsaev (crater)
Patsaev is a lunar crater that lies on the far side of the Moon, to the northeast of the prominent crater Tsiolkovskiy. To the northwest is the smaller crater Lander....

Orbit
In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet around the center of a star system, such as the Solar System...

.This is a worn and eroded crater formation, with features that have become poorly defined and softened due to subsequent impacts and possibly some overlap of ejecta from Tsiolkovskiy and other sources. The inner rim is wider and has a gentler slope along the eastern side. The interior floor is relatively level, but contains some low rises. Only a few tiny craterlets dot the rim and interior of this formation.

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 Lander.

    Topographic map
    A topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines in modern mapping, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features...
