Named for Andre Danjon (1890-1967), a French astronomer who served as Director of the Paris Observatory from 1945 to 1963. In lunar studies, Danjon was particularly noted for his investigation of the intensity of the earthshine seen on the Moon, in the course of which he proposed the Danjon limit for the visibility of thin lunar crescents.
Name originally given by Lamech to a nearside crater, but not approved by the IAU (Whitaker, p 228). Lamech's Danjon was the incomplete formation between nearside craters Gärtner and Kane.
The present Danjon was among the long list of farside names approved by the IAU in 1970 and published in Menzel, 1971.
