Quick Answer
Urbain Le Verrier’s calculations. In 1846 he predicted where Neptune should be, and the planet was found there.
The Full Story
Urbain Le Verrier, a French mathematician and astronomer, used irregularities in Uranus’s orbit to infer the gravitational pull of an unseen planet. His predictions led Johann Galle to observe Neptune in September 1846. This was one of the great successes of mathematical astronomy. The discovery showed the power of Newtonian gravity and perturbation analysis.
