Local Group

The Local Group is a group of galaxies. It includes the Milky Way, Andromeda Galaxy, and Triangulum, along with their satellites and several small galaxies. It in turn is part of the Virgo Supercluster.
==Structure==
Approximately 10,000,000 light-years in diameter, the Local Group has a rough 'dumbbell shape'. Its centre is located somewhere between the Milky Way and Andromeda, at its centre of mass.
It has a total mass of somewhere around 1.3 trillion solar masses.
==Galaxies==
Satellite galaxies have indented bulletpoints. Only those over one kiloparsec in diameter appear.

== Possible Members==
Possible members of the Local Group.
*NGC 3109 - irregular/spiral galaxy, 2.3 billion solar masses, no apparent galactic nucleus
*HVC 127-41-330 - high-velocity cloud, 20,000 light-years in diameter, 80% dark matter, and rotating. Possible dark galaxy.
*Smith's Cloud - high-velocity cloud, 9,800ly by 3,300ly, at least one million solar masses. Possible dark galaxy, will collide with the Milky Way in 27 million years along the Perseus Arm.
