The galaxies are derived from the Greek γαλαξίας (galaxias). In a broad sense, galaxies refer to the operating systems consisting of numerous stellar systems (including the stars' own bodies) and dust (such as nebulae). Reference to the Milky Way, a large galaxy that contains stars, gas interstellar matter, cosmic dust and dark matter, and is bound by gravity. Typical galaxies range from dwarf galaxies with tens of millions of stars to elliptical galaxies with tens of thousands of stars, all running around the center of mass. In addition to individual stars and thin interstellar matter, most galaxies have a large number of multi-star systems, clusters, and various nebulae.
