The Local Group is the name for a group of galaxies,to which our own Milkyway also belongs. In total there are some over 50 galaxies (including dwarf-galaxies) and it stretches over 10 million lightyears. The Local Group itself is part of the Virgo Supercluster. The best known galaxies in the Local Group are our Milkyway and Andromeda. Trying to add the Local Group to the Space Map and ofcourse colonize it, is a good and challenging beginning for humanity in space.
