Eponym	Christopher Columbus

Colombo is a lunar impact crater that lies on the strip of rough continental terrain between Mare Fecunditatis to the east and Mare Nectaris in the west. It is located to the south of Goclenius crater, and northwest of Cook crater.

The rim of Colombo is circular, although slightly indented along the northwest where 'Colombo A' intrudes slightly into the interior. The inner wall is asymmetrical, being much more narrow to the north and northwest and wider to the southeast. The rim is somewhat eroded, and several tiny craterlets lie along the inner wall to the southeast. The small satellite crater 'Colombo B' lies across the south-southwestern rim.

The interior floor of Colombo crater is nearly level, and has been partially covered by deposits of lava. This surface has a lower albedo than the surrounding surface, and has the same dark hue as the lunar mare to the east. At the mid-point of the interior is a semi-circular formation of four central ridges, resembling the remains of a larger mountain mass. The concave side of this feature is facing toward the northwest.

[edit] 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 Colombo crater.
