Explanation

Halley's Comet is named after Edmond Halley, the English astronomer who calculated its orbit and predicted its return in 1758. He was the first to recognize that the comet seen in 1531, 1607, and 1682 was the same object returning periodically. Halley did not discover the comet but correctly predicted its 76-year orbital period.
