Additional Information


  • Named for Gilbert Newton Lewis (1875-1946), an American chemist.
  • Lewis was among the long list of IAU-approved farside lunar feature names published in Menzel, 1971.
  • Lewis was one of two features (the other being Kearons) that Antonín Rükl omitted from his 1972 Maps of lunar hemispheres (illustrating the new IAU nomenclature) because he was unable to find a likely feature at the stated position. - Jim Mosher
  • On the farside map of Hallwag, the name Lewis is printed too much west-southwest of its true location. - DannyCaes Oct 8, 2011
  • Lewis is also the name of a small craterlet on the Taurus-Littrow Valley, aka the landingsite of Apollo 17's LM Challenger. Lewis and Clark (Apollo 17 craters) - "William Clark and Meriwether Lewis began the American exploration of the western territories purchased from France by the young nation. Inspired by Thomas Jefferson, their explorations laid both the psychological groundwork for the future expansion of the United States in the West and the geographical basis for our growth and strength as a free nation." (source: APOLLO LUNAR SURFACE JOURNAL, Eric M. Jones).
  • And who was (or still is?) H. A. G. Lewis? (the editor of THE TIMES ATLAS OF THE MOON).
