Comet

Hallry's Comet was named after the astronomer. Edmond Halley, a friend of Isaac Newton. It was Edmond Halley who discovered that a particular comet would reappear once in about 76 years. To honour his accurate prediction about the reappearance of the comet, scientists named the comet after him.

The tail of the comet can only be seen when it is near the sun. When the sunlight and solar wind hit the gas particles in the comet, a tail is formed.

A comet consists of three parts; a nucleus, coma and tail. The nucleus of a comet is composed of rocks, dust, ice and frozen gases. The streams of dust that form a huge cloud around the nucleus called a coma. The luminous mist that extends from the coma is the tail of the comet.
