From Wikipedia
Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years (5,240 pc), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. It is estimated to contain approximately 10 million stars, and a total mass equivalent to 4 million solar masses,[11] making it the most massive known globular cluster in the Milky Way.
Omega Centauri is very different from most other galactic globular clusters to the extent that it is thought to have an origin as the core remnant of a disrupted dwarf galaxy.
