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
A great comet appeared in the sky above Europe on 1577 AD. Tycho Brahe decided to try and estimate the distance to this comet by measuring its parallax, the effect whereby the position or direction of an object appears to differ when viewed from different positions.
