Additional Information
- From the shadows in LO-IV-132H, Euclides D is 1200-1250 m deep. LO-IV-125H gives a depth of about 1120 m, probably because the shadows are not reaching the deepest part of the floor. - Jim Mosher
Nomenclature
- The name Euclides D was part of the original IAU nomenclature of Blagg and Müller (1935).
- The IAU's newly-formed WGPSN proposed approving the replacement of Euclides D with the name Eppinger, after Czechoslovakian doctor Hans Eppinger (1879-1946) as it had been provisionally assigned on LTO 76D1, and for which it served as the chart name. The change was adopted by the General Assembly in 1976 (IAU Transactions XVIB).
- Subsequently it was brought to the attention of the WGPSN that Eppinger had participated in medical experiments in the Nazi death camps during World War II. As a result the use of Eppinger's name in connection with this crater was officially disallowed in October 2002 (IAU Transactions XXVA).
- In 2006, the IAU Planetary Gazetteer added the list of lunar satellite features from 1982's NASA RP-1097 (IAU Transactions XXVI). Unfortunately, Blagg and Müller's Euclides D was listed there as Eppinger, so the old IAU name was not re-instated at that time.
- The crater briefly known as Eppinger was officially reinstated as Euclides D by the IAU in July 2009.
