Additional Information

  • Dreyer, and the neighboring craters Ginzel (to the north) and Erro (to the south) appear to overlay one of the principal rings of the older Smythii basin, possibly accounting for the somewhat rugged terrain in the area.
  • Portions of the southwest rim of Dreyer, and the terrain to its south, may be visible as a bump (labeled "crater?") on the limb in the LPOD of June 17, 2009. The central part of Dreyer is seen as a notch to the north of the labeled bump. - JimMosher


  • The name honors Johann Ludwig Emil Dreyer (1852-1926), a Danish astronomer best known as compiler/editor of the New General Catalogue of Nebulae and Clusters of Stars. Although born in Denmark, Dreyer spent his professional career in Ireland.
  • Dreyer was in the long list of farside names published by the IAU in Menzel, 1971.
