👤 whose
Whose calculations first predicted an undiscovered planet from Uranus’s motion?
Quick Answer
Urbain Le Verrier’s. His calculations helped predict Neptune’s position in 1846.
The Full Story
Urbain Le Verrier used discrepancies in Uranus’s orbit to infer the presence of another planet tugging on it. In 1846 he predicted where the unknown planet should be, and Neptune was subsequently observed close to that position. The achievement was a triumph of mathematical astronomy. It also demonstrated the power of theory-guided discovery in planetary science.
