Humboldt (crater)
The crater was named after German philologist Wilhelm von Humboldt by the IAU.
Humboldt is one of the largest craters of Upper (Late) Imbrian age.
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 Humboldt. Humboldt N is the largest crater within Humboldt itself, located north of the central peak. Humboldt B is located to the south of Humboldt, on the west rim of the crater Barnard.
Humboldt | Latitude | Longitude | Diameter |
---|---|---|---|
B | 30.9° S | 83.7° E | 21 km |
N | 26.0° S | 80.5° E | 14 km |
Catena Humboldt
Catena Humboldt is a crater chain that extends northeast from crater Humboldt, and it is approximately 162 km long. It was named by the IAU in 1976. It passes between the craters Gibbs and Schorr.
Apollo 12 Views
The Apollo 12 mission in 1969 obtained many photographs of Humboldt crater. In the photos below, the central peaks appear white because of the high-Sun elevation angle. The arcuate fractures within Humboldt are evidence of the forces working on the surface of the Moon to change the lunar topography.
Apollo 15 Views
The Apollo 15 mission in 1971 obtained many more photographs of Humboldt crater.

Eastern crater floor. The mare-type material on the floor contains radial cracks and concentric rilles. A dark-halo area is visible at the lower left corner. Low hills of material that resemble the central peak protrude through the smooth crater floor. Bright-halo craters are also evident. The "doughnut" filling of the crater at the left margin is a rare feature.
