Additional Information

  • Exterior impact melt deposits to E, max of ~100 km beyond rim. Most extensive ejecta, rays and secondary craters to the NE, with max wall slumping on E side of crater, and topographically lowest rim crest to S (Hawke and Head, 1977).
  • Mare area of 1,325 km^2 according to measurements by Jim Whitford-Stark.
  • East of Schrödinger (between Schrödinger and De Forest, see Clementine's photographs of it on LAC 141) is an irregular shaped valley of which the most pronounced (and most shadowed) part is located at 165° to 170° East, 77° South. - DannyCaes May 12, 2009
  • The odd crater Schrodinger W, northwest of Schrodinger itself, looks a bit like one of the craters of the Messier pair in Mare Fecunditatis. A large crater is overlapping a little one, or are both the result of one single oblique impact? - DannyCaes Aug 13, 2014


  • The IAU crater name honors Erwin Rudolf Josef Alexander Schrödinger (August 12, 1887 – January 4, 1961) an Austrian-Irish physicist who achieved fame for his contributions to quantum mechanics, especially the Schrödinger equation, for which he received the Nobel Prize in 1933. In 1935, he proposed the Schrödinger's cat thought experiment.
  • The impact basin is named after the crater.
  • The pronounced valley between Schrödinger and De Forest is unofficially called Vallis Schrödinger-De Forest by D.Caes.
  • Rimae Schrodinger (an unofficial name from D.Caes for the impressive system of rilles on the floor of Schrodinger).
