A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust. Typical galaxies range from dwarfs with as few as ten million stars up to giants with one trillion stars. Galaxies can also contain many multiple star systems, star clusters, and various interstellar clouds.

Our Milky Way Galaxy is 100,000 light years across. Most galaxies range from 30,000 to over 300,000 light years across.
