Cysatus (crater)
Encyclopedia
Cysatus is a lunar
impact crater
that is located in the southern part of the Moon
's near side. It is joined to the norhteastern rim of the larger crater Gruemberger, and intrudes slightly into the interior of that formation. Due south is the larger Moretus
, and to the east is Curtius
. These craters appear foreshortened when observed from Earth
because of their far south location.
This circular crater is slightly unusual for its lack of interesting features. No notable craters lie along its rim or the flat, level interior. The inner walls are devoid of terraces and just slope down to the flat floor, although the width of the inner wall is narrower to the northeast than elsewhere.
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...

Moretus (crater)
Moretus is a lunar impact crater located in the heavily cratered highland region near the south pole of the Moon. South of it is the crater Short, while to the north is Cysatus. To the northwest lies Gruemberger, and Curtius is located to the northeast...

Curtius (crater)
Curtius is a lunar impact crater that is located in the southern part of the Moon. From the Earth the crater appears foreshortened, making it more difficult to observe detail. Nevertheless this is a large crater that can be readily found in even small telescopes. Curtius is located within one...
