  • The Local Group of Galaxies is the small, loose cluster to which our Milky Way Galaxy belongs. It consists of approximately 36 known members, most of which are dwarf galaxies. This Atlas includes identification charts for 32 members for which identification atlases have not hitherto been published. There are numerous atlases of various sorts for the Milky Way Galaxy and there is a published atlas for M31 and its two close companions, M32 and NGC 205 (Hodge 1981).
