Distances of the Local Group member galaxies, from various sources
The distances of the member galaxies of the
Local Group are often not very wellknown.
The following table gives values from various sources, in thousands of
lightyears (kly; e.g., in our database, M31 is 2.9 million light years,
thus 2900 times 1000 light years distant):
