Comet Hyakutake. Optical view of Comet Hyakutake over silhouetted trees. Comet Hyakutake,or 1996 B2,was one of the brightest comets of the 20th century. Comets are mostly formed of water ice and dust. They usually have a diameter of a few kilometres and orbit the Sun with highly elongated orbits. It is only when a comet approaches the Sun that the water ice vaporises to form a tail of gas and dust. This always points away from the Sun because it is blown by the charged particles (the solar wind) which the Sun emits. This photograph was taken on 2nd March 1996 from Ohio,USA | |
