Hansen is a lunar impact crater that is located near the eastern limb of the Moon. At this location the crater appears oval due to foreshortening, but the crater is actually nearly circular. It lies to the northeast of the larger crater Condorcet, and to the south of the smaller Alhazen.
The outer wall of Hansen is sharp-edged, with a slight outward bulge to the southwest. The inner wall drops downward to a shelf of slumped material, then to a slightly bowl-shaped interior. There is a central peak formation at the midpoint of the interior.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Hansen.
