Halley's Comet was named after Edmond Halley, after he predicted the return of a comet known since 240 BC. He published Synopsis Astronomia Cometicae, which stated his belief that the comet sightings of 1456, 1531, 1607, and 1682 were related to the same comet, which he predicted would return in 1758 His predictions were spot on, although he did not live long enough to witness the return of the comet.
