Whose discovery revealed the planet Neptune through mathematics before it was seen?
SpaceAstronomy
Quick Answer
Urbain Le Verrier’s calculations helped predict Neptune’s position in 1846. The planet was then observed close to where he had indicated.
The Full Story
French mathematician Urbain Le Verrier analyzed irregularities in Uranus’s orbit and concluded that an unseen planet must be affecting it. In 1846 he sent his prediction to astronomers, and Johann Galle and Heinrich d’Arrest found Neptune near the predicted location. This was a major triumph for mathematical astronomy. It showed that celestial bodies could be discovered by calculation before direct observation. Le Verrier’s work is one of the classic examples of predictive power in science.
