Halleyâ??s Comet is a periodic comet and returns to earth at roughly every 75 years as predicted by Edmond Halley. Who happened to notice the pattern but was unable to see its return in 1758. In 1910 the comet was especially fantastic, having passed Earth by at about 13.9 million miles, and was photographed for the first time. The return of the comet in 1986 was met by a number of nationâ??s satellites. This fleet of spaceships is sometimes dubbed the "Halley Armada." But was only a spec on the horizon for most of the Earths telescopes as it passed on the other side of the sun opposite Earth at the time.
