Neptune
Astronomers used observational and mathematical skills to discover Neptune. They observed irregularities in the orbit of Uranus and calculated the gravitational influence needed to explain these irregularities, leading them to predict and discover the existence of Neptune.
Johann Gottfried Galle did not discover a planet himself. He was the astronomer who, in collaboration with Urbain Le Verrier, first observed the planet Neptune in 1846 based on Le Verrier's calculations.
