Halley’s Comet closest approach to Earth

Originally shared by Vladimir Pecha

OTD 11 April 1986 Comet Halley made closest approach to Earth, but barely visible to observers.

Comet made its closest approach to Earth this trip, 63 million kilometers, on its outbound journey. Many observers were disappointed because the famous comet was barely visible to the naked eye. Some years are simply better than others, as in 1066 when the comet was so bright that it terrified millions of Europeans. Comet Halley isn’t officially scheduled to visit Earth again until 2061 when it returns on its 76-year orbit. This comet’s closest known approach to the Earth was 3 million miles on 10 Apr 837 AD). Its perihelion (the closest point to the Sun) occurred earlier in the year, on 9 Feb 1986, when it was 88 million km from the Sun, between the orbits of Mercury and Venus. Via TiS.
