halley's comet









































halley's comet or comet halley, officially designated 1p/halley, is a short-period comet visible from earth every 75–76 years. halley last appeared in the inner parts of the solar system in 1986 and will next appear in mid-2061.
halley's comet
halley at first agreed with the longtime consensus that each comet was a different entity making a single visit to the solar system. in 1705, he applied newton's method to 23 cometary apparitions that had occurred between 1337 and 1698. halley noted that three of these, the comets of 1531, 1607, and 1682, had very similar orbital elements, and he was further able to account for the slight differences in their orbits in terms of gravitational perturbation by jupiter and saturn. confident that these three apparitions had been three appearances of the same comet, he predicted that it would appear again in 1758–9. (earlier, robert hooke had identified the comet of 1664 with that of 1618, while giovanni domenico cassini had suspected the identity of the comets of 1577, 1665, and 1680. both were incorrect.) halley's predicted return date was later refined by a team of three french mathematicians: alexis clairaut, joseph lalande, and nicole-reine lepaute, who predicted the date of the comet's 1759 perihelion to within one month's accuracy. halley died before the comet's return; when it returned as predicted, it became known as halley's comet (with the latter-day designation of 1p/halley). the comet next appears in 2061.
