Schwarzschild is an easy to recognize basin because of the two craters Schwarzschild K ("Hedin") and Schwarzschild L on the southern parts of its floor and rim.

Additional Information

  • Listed only as a large crater in Table III of Hartmann and Wood, 1971, this feature was recognized as a basin with rings of 70 and 200 km diameter in Wood and Head (1976). It was also recognized as a basin in Lucchitta (1978).


  • Named for Karl Schwarzschild (1873-1916), a German astronomer.
  • Danny Caes notes that Schwarzschild K (the large crater at the southern part of Schwarzschild's rim) was labeled Hedin on Antonín Rükl's 1972 Maps of lunar hemispheres. Hedin was one of six nearside names that were deemed sufficiently indistinct to merit deleting the nearside names and reusing the names on the farside (IAU Transactions XIVB, 1970). However, subsequent to the October, 1970 printing of provisional ACIC maps illustrating the new IAU farside nomenclature, these six nearside names were reinstated (Menzel, 1971), so Rükl's use of the name Hedin for the farside feature was incorrect (as he notes in the booklet accompanying his maps). - Jim Mosher
