‘A typical comet has three parts: a frozen central part called the nucleus, a fuzzy cloud surrounding the nucleus called the coma (or head) and a tail consisting of gas and dust. The nucleus, usually only a few kilometres across is made of grains of frozen water, methane, ethane, carbon dioxide, ammonia and other gases’

COMET HALE-BOPP

Whipple coined the phrase ‘dirty snowball’. In 1986 the European Space Agency‘s craft Giotto proved that Whipple’s theory is fairly accurate when it took close-up photographs (from a distance of 480 kilometres) of the nucleus of HALLEY‘s comet.
