Description

At a distance of about 15,800 light-years from Earth, Omega Centauri is one of the few globular clusters visible to the naked eye—and appears almost as large as the full Moon when seen from a dark, rural area. It is the brightest, largest and at 4 million solar masses the most massive known globular cluster associated with our galaxy. Of all the globular clusters in the Local Group of galaxies, only Mayall II in the Andromeda Galaxy is brighter and more massive.Orbiting through the Milky Way, Omega Centauri contains several million Population II stars and is about 12 billion years old.
