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 ]
In his 1705 book Synopsis of the Astronomy of Comets, Edmond Halley had calculated that a comet seen in 1682 was the same one seen in 1607 and 1531, which was orbiting the Sun due to Newton's laws of motion, and that it would therefore return in 1758. Both Halley and Newton had since died.
Halley's Comet, named for English astronomer Edmond Halley (1656-1742) who studied it, is considered the most famous one. It takes a 76-year orbital lap around the sun.
Halley’s Comet takes about 75 years to orbit our sun once, and according to NASA, the comet isn’t expected to enter the inner solar system again until 2061.

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 ...
The Orionids meteor shower is produced by Halley's Comet, which was named after the astronomer Edmund Halley and last passed through the inner Solar System in 1986 on its 75–76 year orbit. [10] When the comet passes through the Solar System, the Sun sublimates some of the ice, allowing rock particles to break away from the comet.
