Comet Brooks, 1893. 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. The direction of the tail indicates the direction of the Sun. Also known as C/1893 U1, 1893 IV, and 1893c, this comet is here seen in the constellation of Coma Berenices. It was observed by E. E. Barnard (US astronomer Edward Emerson Barnard) from the Lick Observatory, USA, on 21 October 1893. |
