Edmond Halley (1656–1742) was an English astronomer, mathematician, and physicist who served as the second Astronomer Royal in Britain. He is best known for calculating the orbit of Halley’s Comet, predicting its return in 1758, a prediction confirmed after his death.
Key Contributions and Discoveries:
Comet Prediction: Halley demonstrated that comets of 1531, 1607, and 1682 were the same object, establishing that comets orbit the Sun.
