What was the experiment that confirmed Halley's hypothesis?

The experiment that confirmed Halley's hypothesis regarding the nature of comets was conducted by Edmond Halley himself in 1705. He predicted that the Great Comet of 1682 would return in 1758, based on its orbit. When the comet reappeared as predicted, it was named Halley's Comet in his honor, validating his theory that comets could have predictable orbits similar to planets. This observation established the notion that comets are not random but instead follow specific paths through the solar system.
