Basin Pole South-Aitken

The basin Pole South-Aitken , corresponds to largest the Cratère of impact of the surface of the the Moon, and even of the Solar system, with approximately 2500 kilometers in diameter for 13 kilometers of depth. The only basin of impact which approaches some by its size is the Hellas Planitia on Mars, with 2100 kilometers in diameter.

This basin was named name of the two places of the Moon located on the sides opposite of the crater: the crater Aitken on the northern slope, and the South pole of the Moon on the southern slope. The external crown of the crater can be seen since the Ground in the shape of an immense chain of Montagne S located close to the limb - horizon - south of the Moon, and sometimes called " mountains of Leibnitz " (although this name was never recognized officially by the international astronomical Union (UAI).
