Comet Encke (2P/Encke). Comets are bodies of ice and dust that enter the inner solar system from the outer solar system. As they approach the Sun,the heat boils the ice,producing a coma around the nucleus,along with a tail stretching out behind it. Comet Enke is a periodic comet that completes an orbit of the Sun once every three years,the shortest period of any known comet. First recorded by Pierre Mechain in 1786,it was first recognized as a comet when its orbit was computed in 1819 by Johann Franz Encke. This image was obtained on 30 October 2013 | |
