Comet Hyakutake in the night sky. A comet consists of ices and dust,and orbits round the Sun. Near the Sun,the icy core melts and boils into space. The solar wind then blows the resulting gases into a tail,pointing away from the Sun,which may be millions of kilometres long. The particles of dust and ice glow and reflect sunlight to form a bright display,sometimes lasting for several months. Comet Hyakutake (also known as 1996 B2) was among the brightest comets of the 20th century,passing 15 million kilometres from Earth on 25 March 1996. It is a long-period comet: it last appeared at least 10,000 years ago,and its next visit will be in about 20,000 years time | |
