Description

La Pérouse is one of a relatively large number of limb craters that are not often observed and hence often require a map to identify. La Pérouse is limbward of Langrenus in a seldom observed area. At 77 km in diameter it is typical complex crater with terraces, central peak and relatively flat foor. La Pérouse is a fairly fresh crater - although it does have a later impact on its floor - but the Clementine high Sun view shows it has no ray system and thus is probably more than a billion years old. There are slumped terraces and a significant scarp at the top of the eastern wall. This is probably another steep place on the Moon. (Modified from Oct 11, 2006 LPOD.)- tychocrater Jun 28, 2007

(IAU Directions) LA PEYROUSE.--A much foreshortened walled-plain, 41 miles in diameter, close to the limb, S.E. of Langrenus. There is a longitudinal ridge on the floor. Between it and Langrenus are two large ring-plains with central mountains, and on the N.W., La Peyrouse A, a bright crater, adjoining which is La Peyrouse DELTA, one of the most brilliant spots on the moon.

Additional Information


Nomenclature

  • Named for Jean François de Galaup, comte de La Pérouse (August 23, 1741–1788?), a French Navy officer and explorer whose expedition vanished in Oceania.
  • This feature was catalog entry 4767 in the original IAU nomenclature of Blagg and Müller, where it was spelled Lapeyrouse, a name attributed to Mädler.
  • It was changed to La Pérouse in IAU Transactions XIB (1961).
  • NASA SP-241 (not an official IAU document) insists the correct way to capitalize this name is "la Pérouse" (p. 538). The IAU does not seem to agree.
  • The name La Pérouse is absent in the first edition of the book Who's Who on the Moon; a Biographical Dictionary of Lunar Nomenclature by Elijah E. Cocks and Josiah C. Cocks (Tudor Publishers, 1995). Error detected by Danny Caes.
