Distances of the Local Group member galaxies

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):
