Description
Description: Elger
(IAU Directions) DELAMBRE.--A conspicuous ring-plain, 32 miles in diameter, a little S. of the equator, in E. long. 17 deg. 30 min., with a massive polygonal border, terraced within, rising on the E. to the great height of 15,000 feet above the interior, but to little more than half this on the opposite side. Its outline approximates to that of a pentagon with slightly curved sides. A section on the S.W. exhibits an inflexion towards the centre. The crest is everywhere continuous except on the N., where it is broken by a deep crater with a bright rim. The north-westerly trend of the ridges and hillocks on the W. is especially noteworthy. The central peak is not prominent, but close under it on the W. is a deep fissure, extending from near the centre, and dying out before it reaches the S. border. At the foot of the N.W. glacis there are traces of a ring with low walls.

Nomenclature
- Named for Jean Baptiste Joseph Delambre (September 19, 1749 in Amiens – August 19, 1822 in Paris), a French mathematician and astronomer. Named director of the Paris Observatory and professor at the Collège de France, Delambre was one of the first astronomers to derive astronomical equations from analytical formulas, was the author of Delambre's Analogies and, after the age of 70, also the author of works on the history of astronomy.
- This name was one of eight names introduced by Lohrmann (Whitaker, p. 119). All of Lohrmann's names were adopted by the three "authorities" cited in Mary Blagg's Collated List, and incorporated into the original IAU nomenclature of Blagg and Müller (1935).
- Delambre Epsilon (elevation south of Delambre) (see page 123 in Tony Dethier's Maanmonografieen) (the name Delambre Epsilon is not mentioned on Chart 57 in the Times Atlas of the Moon).
