Detailed explanation-1: -Graham and Eric Hintz suggested that one of the earliest known sightings of Halley’s comet may have occurred around 466 B.C. in the skies over Greece.
Detailed explanation-2: -The comet, officially called 1P/Halley, is named after English astronomer Edmond Halley, who examined reports of a comet approaching Earth in 1531, 1607 and 1682. He concluded that these three comets were actually the same comet returning over and over again, and predicted that it would return in 1758.
Detailed explanation-3: -Isaac Newton and Edmond Halley In 1682, around the time Halley was observing the most famous comet in the world, he was also deeply involved in the study of Johannes Kepler’s work on planetary motion, namely that of elliptical orbits of planets around the Sun.
Detailed explanation-4: -The ice and gas begin to boil of its surface and gets blown back by the solar wind of the sun. It then starts to look like a comet. The last time Halley’s comet was close to the sun was in 1986, and so the next time will be in 2061. You won’t be able to see Halley’s comet until then.
