has definition A conglomeration of about twenty galaxies including our own Milky Way.has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:31:07.0
has definition The cluster of galaxies to which our Galaxy belongs. It is a poor, irregular cluster with some 20 certain members: three spirals (the Galaxy, M31, and M33); four irregulars (LMC, SMC, IC 1613, and NGC 6822); and about 13 intermediate or dwarf ellipticals (NGC 147; NGC 185; NGC 205; M32; the Sculptor, Fornax, Leo I and II, UMi, and Draco systems; and three companions to M31 discovered by van den Bergh in 1972). It may also include several other dwarf galaxies as well as the giant elliptical Maffei 1. The total mass of the Local Group is less than 1.5 times the combined masses of the Galaxy and M31.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:31:07.0
has definition The system of galaxies to which our Milky Way galaxy belongs is a small group, containing only two large spirals (our galaxy and the Andromeda galaxy, Messier 31) and twenty or more smaller systems.has source: Silk, J. 1990 The Big Bang, W. H. Publishers, New York, 2001-09-27 09:31:07.0
has definition The cluster of galaxies of which our own, the Milky Way, is one. Its radius is estimated at 106 parsecs. Largest of the Group is the Andromeda galaxy.has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:31:07.0
