Unknown
Notice a small crater, located on the floor of Arzachel, on the right of the central mountain. This is called Arzachel A. It has a diameter of 10 km.
Note terraces on the interior walls of the crater, very well shaped, in waves.
Arzachel crater (97 km) on the Moon, is a special one because it does not look like other craters in the area, which have large and lower margins like Albategnius, Ptolemaeus and even Alphonsus for exemple.
Arzachel my opinion, is more like the crater Copernicus, which has a diameter of 93 km. Both have terraces, central peaks, and are similar in shape, but Copernicus, although smaller, is out much more in evidence, being very easy to locate with the telescope, because it is located on a large smooth area of Insularum basin, and for the very bright rays from the impact that formed the crater. But Arzachel has no rays, and it is not located on a large area, but between many bigger and smaller craters, on the highlands of the Moon.
Above, is a photo of the crater Copernicus from April 13, 2011. Note the similarity with Arzachel crater.
