Inner crater, Einstein A, is 51 km in diameter (IAU diameter, adopted from NASA RP-1097 in 2006, confirmed by LTVT measurement - Jim Mosher).

Additional Information

  • Depth data from Kurt Fisher database
    • Westfall, 2000: 1.85 km
  • Lunar Orbiter III - at the end of its successful mission - crashed into the southwest edge of Einstein in 1967.
  • Coordinates and diameter are from Rükl The Moon, which in turn appear to have been copied from NASA RP-1097. The IAU values are: Lat: 16.3°N, Long: 88.7°W, Diam: 198 km. Careful measurement of Lunar Orbiter frames IV-187M, IV-188M, IV-190M and IV-188H with LTVT register to the 1994 ULCN suggest that the RP-1097 values are better, although the center longitude is perhaps 88.4 W. Einstein's rim crest appears highly eroded in the Lunar Orbiter views, so its diameter is poorly defined, but again the RP-1097 value seems better. Where the IAU diameter of 198 km came from is not known. - Jim Mosher

  • Einstein A: TSI = 30, CPI = 30, FI = 25; MI =85 Smith and Sanchez, 1973
  • The central crater, Einstein A, is catalogued as a typical Floor Fractured Crater (FFC), but... one should take a look at the floor of the larger surrounding main crater Einstein to detect lots of small unnamed FFCs! - DannyCaes Aug 18, 2015


  • Albert Einstein (March 14, 1879 – April 18, 1955) was a German-born theoretical physicist who is best known for his theory of relativity and specifically mass-energy equivalence, E = mc2.
  • Name originally proposed by Wilkins for Simpelius D but not accepted by IAU; shifted to a different crater in Rectified Lunar Atlas (1963) and approved by IAU in 1964 (Whitaker, 1999, p235).
