Halley's Comet's
Halley's comet is the most famous of all comets, recorded by Chinese astronomers in 467 BC (and possibly in 611 BC). It is a periodic comet orbiting the Sun in a retrograde direction with a period of 76 years. It is named for the English astronomer Edmund Halley, who applied to comets Newton's theory of planetary motions and correctly predicted the return of the bright comet in the year 1758.
