  • 76% of Local Group galaxies are dwarf galaxies.

  • 90% are invisible to the naked eye and 66% are 100 times dimmer than the limit of visibility.

  • Local Group galaxies appear to be clustered around the two largest members of the group: The Milky Way and the Andromeda (M31) galaxies which are separated by about 670 kpc (2 Mlyrs). The entire Local Group has a diameter of about 5 Mlyrs.



80% of Local Group Galaxies are less than 0.01 LMW and 33% are less than 0.0001 LMW
