“Our Galaxy is part of the Local Group (LG) of galaxies, a small, gravitationally bound group of galaxies consisting of a few bright spiral galaxies and about 2 dozen dwarf galaxies. Our LG lies in the outskirts of the Local Supercluster, a flattened structure of about 30 Mpc, centered on the Virgo galaxy cluster containing a few thousand galaxies including numerous dwarfs..

..a major part of the peculiar motion of the LG is generated by a few average, but nearby, galaxies. In this sense, the detection of other nearby galaxies hidden by the obscuration of the Galaxy can be as important as the detection of entire clusters at larger distances.
