May 23, 2024 · The honour of predicting it goes to mid-19th-century astronomers Urbain Le Verrier and John Couch Adams. They noticed that Uranus (which was only discovered about 60 years earlier) had ...
May 13, 2024 · John Couch Adams and Urbain Le Verrier reached, independently but using essentially the same perturbation theory techniques, a predicted position on the celestial sphere for the supposed perturber1, which was found to be very close to the actual position spotted in September of 1846 by Johann Gottfried Galle and Heinrich Louis
6 days ago · Calculations by John Couch Adams and Urbain Le Verrier both predicted the general position of the planet. In 1846, Le Verrier sent his position to Johann Gottfried Galle, asking him to verify it. The same night, Galle spotted Neptune near the position Le Verrier had predicted. Not every comparison was successful.
6 days ago · In 1846, John Couch Adams, a British mathematician and astronomer, determined the position of Neptune, using only mathematics. Around the same time, the French astronomer Urbain Le Verrier calculated the planet's location independently of Adams.
6 days ago · In 1781, with the help of a telescope, English astronomer William Herschel found another planet. Following the pattern of naming planets after Roman gods, it was eventually named Uranus. Finally, in 1846, English mathematician John Couch Adams and French mathematician Urbain Jean Joseph Le Verrier found another planet at the same time.
6 days ago · 1846 – Urbain Le Verrier and John Couch Adams, studying Uranus' orbit, independently prove that another, farther planet must exist. Neptune was found at the predicted moment and position. 1855 – Le Verrier observes a 35 arcsecond per century excess precession of Mercury's orbit and attributes it to another planet, inside Mercury's orbit ...
Johann Galle is most closely associated with discovering the planet, but without the assistance of John Couch Adams and Urbain Le Verrier, it would not have been possible. Neptune is the smallest and most remote of the gas giants.
