Answer:
The word ‘comet’ comes from the Greek komhth comètè (long-haired), from which we also get the word ‘comb’. Loosely, a comet appears as a hairy star. For millennia comets have been associated with disasters. Two examples are the apparitions of Halley’s Comet during the Battle of Hastings in 1066 and the destruction of Jerusalem in AD 70. Comets really do appear mysterious. While the stars, the Sun, the Moon, and the five naked eye planets all follow regular and predictable motions, comets appear suddenly, quickly move in an erratic fashion, and then abruptly disappear, apparently never to be seen again.
Comets contain dust, ice, carbon dioxide, ammonia, methane and more. Astronomers think comets are leftovers from the material that initially formed the solar system about 4.6 billion years ago.
