Halley's Comet Halley's Comet or Comet Halley, officially designated 1P/Halley,[2] is a short-period comet visible from Earth every 74â€“79 years.[2][10][11][12] Halley is the only known short-period comet that is regularly visible to the naked eye from Earth, and the only naked-eye comet that might appear twice in a human lifetime.[13] Halley last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061.[14]
Corona Spectroscopy measurements indicate strong ionization and plasma temperature in excess of 1,000,000 kelvins,[1] much hotter than the surface of the Sun.
