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.
Heaven's Gate was an American new religious movement known primarily for the mass suicides committed by its members in 1997. Commonly designated a cult, it was founded in 1974 and led by Marshall Applewhite (1931–1997) and Bonnie Nettles (1927–1985), known within the movement as Do and Ti.
Halley died before the comet's return; [39] 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.

The famous Halley’s comet is about halfway through its roughly 76-year orbit of the sun, having reached its farthest point from its host star in December 2023. The comet won’t be visible in ...
Comet Hale–Bopp (formally designated C/1995 O1) is a long-period comet that was one of the most widely observed of the 20th century and one of the brightest seen for many decades.

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.
