Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, [16] appearing every 72–80 years, [17] though with the majority of recorded apparations (25 of 30) occurring after 75–77 years.
The comet's periodicity was first determined in 1705 by English astronomer Edmond Halley, after whom it is now named. During its 1986 apparition, Halley's Comet became the first comet to be observed in detail by spacecraft , providing the first observational data on the structure of a comet nucleus and the mechanism of coma and tail formation.
Minor planets in comet-like orbits similar to HTCs that never come close enough to the Sun to outgas are called centaurs. HTCs are named after the first discovered member, and the first discovered periodic comet, Halley's Comet, which orbits the Sun in about 75 years, and passing as far as the orbit of Neptune.
The name was inspired by the supposedly official pronunciation of Halley's Comet and was suggested by Bob Johnson, program director at radio station WPWA where Bill Haley had a live radio program from 12:00 noon to 1:00 p.m.

In around the mid-1940s, Bill Haley performed with the Down Homers and formed a group called the Four Aces of Western Swing. The group that later became the Comets initially formed as "Bill Haley and the Saddlemen" c. 1949 –1952, and performed mostly country and western songs, though occasionally with a bluesy feel.
The Orionids — one of two annual meteor showers from Halley's comet — peak early Monday. A bright waning moon may make them difficult to spot. Moonlight may hamper views of the Orionid meteor ...
The second and final meteor shower of spring is about to peak, and it will present a unique opportunity to enjoy a well-known comet that is billions of miles away from Earth.
