Omega Centauri or NGC 5139, is a globular cluster in the constellation of Centaurus that
was discovered by Edmond Halley in 1677. Located at a distance of 15,800 light-years,
it is the largest globular cluster in the Milky Way galaxy 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 suns..
Omega Centauri is so distinctive from the other galactic globular clusters that it is thought to
have an alternate origin as the core remnant of a disrupted dwarf galaxy.
