Neptune.
When perturbations in the orbit of Uranus were observed, Le Verrier proposed that this was caused by another planet. He used mathematics to calculate the orbit and position of this planet; it was observed through telescopes and named Neptune.
Years later, perturbations in the orbit of Mercury were observed. Le Verrier once again thought that another planet caused this, he calculated the orbit and named the planet Vulcan. There's no planet Vulcan however; the orbit of Mercury is 'disturbed' by other factors then unknown.
The calculations for Neptune were also done in England by John Couch Adams. He sent his results to the Astronomer Royal, Airey, but he put them in a drawer and forgot about them :).
Uranus was discovered by Sir William Herschel in 1781. Herschel was probably the most famous astronemer of the 18th century. In addition to discovering the planet Uranus, he also observed and cataloged over 800 double stars and 2,500 nebulae. He was the first astronomer to correctly describe the spiral structure of our Milky Way galaxy.
Unexpected changes in the orbit of Uranus led astronomers to deduce that its orbit was subject to gravitational perturbation by an unknown planet

The planet Uranus was discovered in 1781 by William Herschel. That was about 129 years ago.
Galileo Galilei did - He proved that the planets orbit the Sun, and that Earth is a planet, too.
