Galaxy Group		  

The Local Group is the galaxy group that includes the Milky Way. It comprises more than 54 galaxies, most of them being dwarf galaxies. Its gravitational center is located somewhere between the Milky Way and the Andromeda Galaxy.

NGC 3109 Sub Group

NGC 3109 is the dominating member of a small group of dwarf galaxies, all of them Local Group member candidates, which also contains Sextans A, Sextans B, the Antlia Dwarf and perhaps Leo A.

It is still not finally clear if these galaxies are gravitationally bound to the Local Group of Galaxies, thus forming a subgroup of the Local Group, or if this is the nearest independent small group of galaxies.
