In 1677, Edmond Halley gave the name Omega Centauri (ω Cen) to what he thought was a star in the Centaurus constellation. Later in 1830 John Herschel realized that it was in fact a globular cluster that could be resolved into individual stars. We now know that Omega Centauri is the most massive globular cluster in the Milky Way: it is. Omega Centauri, the largest globular star cluster of the Milky Way, contains about 10 million stars. Is a star cluster bigger than a galaxy?

Omega Centauri has several characteristics that. The Alpha Centauri is a triple-star system. It contains thee Proxima Centauri, which is also called Tollman, meaning foot of centaur. The magnitude of the system is -0.28 and the constellation lie around 4.4 light years from the Earth. Inside the Alpha Centauri system, the secondary and the primary stars are yellow-hued stars

There is less than you may think, about 150 the biggest of which being Omega Centauri. But don't think that because of this decently small number that there is not a lot of stars inside these. Another possibility is that stars in the center of Omega Centauri have elongated orbits that would make the stars closest to the center appear to speed up. For both alternative scenarios it is very hard to get stars to behave that way, either the burned-out stars really bunched up in the center or many stars with very elongated orbits, Noyola.

Omega Centauri is an intimate place for stars. The cluster contains millions of stars packed into a ball a few dozen light-years across. On average, the planets in its core are separated by just one-sixth of a light-year. By comparison, the closest star system to the Sun is more than four light-years away. That means the skies of any planet in the cluster would be ablaze wit These peculiarities have led astronomers to suggest that Omega Centauri may not be a globular cluster at all, but a dwarf galaxy stripped of its outer stars by an earlier encounter with the Milky Way
