Halley's Comet

Summary

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, appearing roughly every 75–76 years, though with the majority of recorded apparitions 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. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley.
