Description


Description: Elger

(IAU Directions) LONGOMONTANUS.--A much larger walled-plain, S. of Wilhelm I. It is 90 miles in diameter, with a border much broken by depressions, especially on the N.W. At one peak on this side it rises to the tremendous altitude of 13,000 feet above the floor, and at peaks on the E. more than 1,000 feet higher. There is a crowd of ring-plains on the N.W. quarter of the interior, and some hills and craterlets in other parts of it. It is also crossed by rays from Tycho.

Trivia
  • A collection of six closely packed squarish depressions at 337.70° Longitude, -52.35° Latitude creates a curious wafer-like pattern in the Clementine images (at the southern slopes of Longomontanus). See: Map-A-Planet. - DannyCaes DannyCaes Nov 25, 2007

Nomenclature

  • Named for Christen Sørensen Longomontanus (or Longberg) (October 4, 1562 – October 8, 1647), a Danish astronomer. The name Longomontanus was a Latinized form of the name of the village of Lomborg, Jutland, Denmark, where he was born. Engaged by Tycho Brahe in 1589 as his assistant in his great astronomical observatory of Uraniborg, he rendered invaluable service for eight years.
  • According to Whitaker (p. 196), van Langren introduced the name Longomontani as a label for either the modern day Mason or Plana on his 1645 lunar map.
  • Hevelius later seems to have labeled it Mons Annae (Whitaker, p. 202), although the latter name may have included the modern Wilhelm.
  • Riccioli assigned the name Longomontanus to the present crater in 1651, and that usage has continued ever since (Whitaker, p. 213).
