AstronomyPlanet discovery
Quick Answer
Urbain Le Verrier’s calculations helped predict Neptune in 1846. His mathematical work pointed astronomers to the planet’s location before it was observed.
The Full Story
Urbain Le Verrier, a French mathematician, used irregularities in Uranus’s orbit to infer that another planet must be disturbing it. In 1846, his calculations led Johann Galle and Heinrich d’Arrest at the Berlin Observatory to Neptune, found very near the predicted position. This was one of the great triumphs of mathematical astronomy in the 19th century. Neptune was observed on September 23, 1846, confirming the power of orbital prediction.
Key Facts
1.Neptune was observed on 23 September 1846
2.Le Verrier’s predictions were based on Uranus’s orbital deviations
3.Johann Galle made the observation in Berlin
