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 parsecs ), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. [ 10 ]
Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley. Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC, but it was not until 1705 that the English astronomer Edmond Halley understood that these appearances ...

In 1718, Edmond Halley found that some stars had significantly moved from their ancient astrometric positions. [74] In the 1830s, Thomas Henderson discovered the true distance to α Centauri by analysing his many astrometric mural circle observations. [75] [76] He then realised this system also likely had a high proper motion.
