SpaceAstronomy History
Quick Answer
Neptune was the first planet discovered through mathematical prediction. It was observed in 1846 after calculations by Urbain Le Verrier and John Couch Adams.
The Full Story
Neptune is the only planet discovered largely because mathematicians predicted it should exist. Irregularities in Uranus’s orbit led Urbain Le Verrier in France and John Couch Adams in Britain to calculate the position of an unseen planet. Johann Galle observed Neptune on 23 September 1846, close to the predicted location. This was a major triumph for celestial mechanics and showed how gravity could reveal a hidden world. Neptune’s discovery is one of the classic moments in science history.
