Comet C/2001 Q4. This comet reached perihelion (its closest point to the Sun) on 15 May 2004. A comet is a ball of water ice and dust,which has a highly elliptical orbit around the Sun. As comets approach the Sun,they develop a tail of vaporised gas and dust that always points away from the Sun due to the solar wind. This comet was discovered by the Near Earth Asteroid Tracking system (NEAT) project in 2001. Photographed from Angola | |
