It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
Who and when was Neptune discovered?
When Neptune was discovered how was its position predicted?
In 1846, the planet Neptune was discovered after its existence was predicted because of discrepancies between calculations and data for the planet Uranus. Astronomers found the new planet almost exactly at the position predicted by the calculations of Urbain Jean Leverrier.

Who discovered Uranus and Neptune?
John Herschel almost discovered Neptune the same way his father, William Herschel, had discovered Uranus in 1781: by chance observation. In an 1846 letter to Wilhelm Struve, John Herschel states that he observed Neptune during a sweep of the sky on July 14, 1830.
How was the position of planet Uranus predicted?
The hunt for a possible new planet was triggered in 1821, when Alexis Bouvard published astronomical tables for the orbit of Uranus. The tables predicted the planet’s position based on Newton’s laws of motion of gravitation, and astronomers began comparing their observations to those tables.
How did astronomers discover Neptune?
Neptune, generally the eighth planet from the sun, was postulated by the French astronomer Urbain-Jean-Joseph Le Verrier, who calculated the approximate location of the planet by studying gravity-induced disturbances in the motions of Uranus. …
