Riemann J (Moon)

Satellite Feature of Riemann

Named after Georg Friedrich Bernhard Riemann - German mathematician (1826-1866).

Riemann is a lunar crater that is located near the northeastern limb , and can just be observed edge-on when libration effects bring it into sight. It lies to the east-northeast of the large walled plain Gauss. To the southeast, beyond sight on the far side, is the crater Vestine. This is a heavily battered and eroded formation that is only a remnant of its former self. (wikipedia entry)
