has definition A tightly packed, symmetrical group of thousands of very old (pure Population II) stars. The stellar density is so great in the center that the nucleus is usually unresolved. The stars within a globular cluster orbit each other because of their mutual gravity. | ![has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, has URL: http://www.seds.org/messier/glob.html, 2001-09-27 09:30:56.0 has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, has URL: http://www.seds.org/messier/glob.html, 2001-09-27 09:30:56.0](facet.gif) |
