How did Halley's Comet get its name?

Halley's comet got its name from Sir Edmund Halley who, using Newton's laws of motion, predicted that the comet seen in 1531, 1607, and 1682 would return in 1758. Unfortunately, Halley died before seeing the comet return, but when it returned just as he had predicted, the comet was named in his honour by French astronomer Nicolas Louis de Lacaille in 1759.
Halley's Comet was named for Edmond Halley, the English astronomer who identified it as a periodic comet.
