A Fact About Comets!

Just Wanted To Know About A Fact About Comets, Space's Finest Treasure!

• The appearance of Halley's Comet is such a rare and spectacular event that it is only natural for it to have been referenced in popular culture during the year it appeared—which, considering the fact that it only occurs once every 76 years—means that all of the movies, videogames, and TV shows which featured it as a plot point absolutely had to have been made in 1985 or 1986.  The only other years in which mankind knew the Comet would appear and therefore use it as something other than a portent of doom in fiction would have been in 1835 or 1910 (and therefore before movies and television existed, although ample photographic evidence exists of the 1910 apparition) or in 2061 or a later date (which haven't happened yet).
