The Local Group of Galaxies  

In General > s.a. milky way galaxy [and immediate surroundings]; dark matter on cosmological scales; MOND.
* Composition: It consists of 36 galaxies as of Jan 2000, more than 54 as of Jul 2012, including M31 Andromeda (65% of mass), M32 dwarf elliptical satellite of M31, Milky Way (30%), the Magellanic Clouds (dLMC = 50,600 ± 2,400 pc), recently discovered Cetus dwarf spheroidal, SagDIG, etc; It looks "isolated in the general field," as Hubble claimed.
* M31 system: The dwarf satellite galaxies of the Andromeda galaxy are also aligned in a thin and kinematically coherent planar structure.

Satellites of the Milky Way Galaxy
* In general: The Milky Way galaxy has some 30 dwarf satellite galaxies, distributed in a highly inclined Disc of Satellites (DoS), and about 150 globular clusters, with the young halo clusters and star streams distributed similarly to the DoS; Overall, the MW is surrounded by a Vast Polar Structure (VPOS) of subsystems; 2015, A number of new ultrafaint satellites found, associated with the Magellanic Clouds.
* Large Magellanic Cloud: Less evolved than the Milky Way; d ~ 163,000 ± 2.2%, as of 2013); It contains significantly less heavy elements.
