Birkhoff Basin
(unofficial name; IAU crater name: Birkhoff; 345 km diam)
Lat: 58.7°N, Long: 146.1°W, Main ring diam: 325 km, Depth: km, Rükl: (farside) | |
Right: Clementine, Clementine LIDAR Altimeter texture from PDS Map-a-Planet remapped to north-up aerial view by LTVT. The dot is the center position and the white circle the main ring position from Chuck Wood's Impact Basin Database. Grid spacing = 10 degrees.

Additional Information
- Depth estimates of 4.76 and 3.83 km
- Rim height 1.27 km
- Discovered by Hartmann & Wood (1971)
- Birkhoff Z mapped as Copernican by USGS.
Nomenclature
- The IAU crater name honors George David Birkhoff (March 21, 1884 - November 12, 1944), an American mathematician best known for what is now called the ergodic theorem. Birkhoff was one of the most important leaders in American mathematics in his generation, and during his prime he was considered by many to be the preeminent American mathematician.
- Birkhoff was in the long list of farside names published by the IAU in Menzel, 1971.
- The informal basin name is derived from that of the crater.
