Local Group (SCAI)

The Local Group is the galaxy group that includes the Milky Way. The Local Group comprises more than 54 galaxies, most of them dwarf galaxies. Its gravitational center is located somewhere between the Milky Way and the Andromeda Galaxy. The Local Group has a diameter of 10 Mly and has a binary distribution

The Union Astrograpic Society recognizes the Local Group and designates it UAS LOCAL GROUP It contains 64 Local Group Galaxies of which Andromeda is its biggest member. It also contains Trans Galactic Void. Or space between the Galaxies.

The first Survey project :  Local Group Survey Project, first conceived in 4956 OTT sent manned and automated probes to several galaxies of the local group.

The second Survey Project : Part of the Gate Mapping Project - Local Assessment, Contact and Threat assessment -LACTA of 5039 OTT is currently active.
