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...

, to the northeast of the prominent crater 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...

. To the northwest is the smaller crater Lander

Lander (crater)

Lander is a lunar crater that is located just to the north-northeast of the prominent Tsiolkovskiy, on the far side of the Moon.Attached to the northeastern rim of Lander is Volkov J, which is joined with Volkov to the north. Just to the southeast of Lander is Patsaev...

.

This is a heavily damaged crater that now appears as little more than an irregular depression in the surface. Both the outer rim and interior floor are streaked by jumbled ridges of material that are radial to Tsiolkovskiy. Most likely this is ejecta deposited during Tsiolkovskiy's formation.

Kira

Within Patsaev Q is a tiny crater that was officially designated Kira by the IAU. Kira is a Russian feminine name – the crater is not actually named for any specific person. The selenographic coordinates of this feature are 17.6° S, 132.8° E, and the diameter is 3 km.

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 Patsaev.

Patsaev K	18.8° S	134.5° E	53 km
Patsaev Q	17.8° S	132.7° E	34 km

The satellite crater Patsaev Q is located just to the southwest of Patsaev. In the past it was suggested that this feature be renamed Chenier, in honor of André Marie Chénier

  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...
