On May 19, 1910 the Earth passed through the tail of Halley’s Comet, the closest the earth has ever come to a comet during recorded human history.  The word comet is an English noun like the word planet that comes from an Ancient Greek adjective. The word comet came from Early French (circa 1200) comète via the Ancient Greek (aster) kometes which meant a (star) with long hair. The adjective kometes came from the Ancient Greek word kome meaning a head of hair. Like planet, the word for star was dropped and only the modifier remained.  A comet is defined as a celestial body in the solar system, usually with an eccentric orbit, corona and tail.
