playing a visible atmosphere or coma, and sometimes also a tail According to

appearing once in every 76 years. Halley's Comet has been named after an English
astronomer, mathematician, meteorologist and physicist, Edmund Halley. He was
born in 1656 and was exactly the sort of person to become a scientist in the
seventeenth century. His first success came when he was only twenty three years
old. Like other scientists of his period, Halley had many different interests such as
spending most of his time on lunar observations and was also interested in the
problems of gravity. He was appointed Astronomer Royal for his work on star
maps, eclipses, orbits and the movements of the moon Despite all this activity,
Halley still found time to observe and measure a number of comets. He used
Newton's law of Universal Gravitation to work out the actual path of a comet
through space. Halley died in 1742 at the age of 85.
