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...

. This location makes the crater difficult to observe due to foreshortening. The crater is also illuminated at a very low angle, when it is in the sunlit side. Demonax lies just to the north of the crater Scott
Scott (crater)
Scott is a lunar impact crater near the south pole of the Moon. Its location close to the lunar limb hinders observation, both from the foreshortening of the crater as seen from Earth and from the limited sunlight that enters the basin. In fact the northern end of this crater is in near perpetual...

, one of the south polar formations. To the north-northwest is Boguslawsky
Boguslawsky (crater)
Boguslawsky is a lunar impact crater that is located near the southern lunar limb. It lies to the northwest of the slightly larger crater Demonax, and southwest of the concentric crater Boussingault. Due to its location, this crater appears very oblong in shape because of foreshortening.The floor...

This crater has a worn and eroded rim, with several small craters lying along the edge and the inner walls. The southeast rim in particular has a notable collection of impacts, including the satellite crater Demonax A which intrudes into the interior floor. The crater bottom has been resurfaced, leaving a flat, level floor. However there is a group of central peaks near the mid-point, and the northern part of the floor is rough and hummocky. The remains of some terraces are visible along the western interior floor.

Due to the low angle of sunlight reaching this crater, the inner wall along the north side of the crater receives very little sunlight.

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 Demonax.
