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. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061.
