                                                Halley’s Comet

Halley’s Comet is a periodic comet. It returns to the earth’s vicinity about every 75 years. This comet is named after an English astronomer Edmond Halley. Edmond Halley observed it in 1682 and examined the reports of this comet approaching earth in 1531, 1607 and 1682. He confirmed that they are not three different comets. It is a periodic comet that is approaching earth again and again. Halley also predicted that it will be seen again in 1758. The most recent appearance of Halley’s Comet was in 1986. This comet is dark and reflects only 4% of the sunlight it receives.
