Neptune is the first planet discovered by astronomical calculation, when it was subsequently observed with a telescope on September 23, 1846 by astronomer Johann Galle within a degree of the position predicted by using astronomical calculations by astronomer Urbain Le Verrier
. It has 13 moons, with its largest moon as Triton.
1846 - Eighth planet Neptune is confirmed by Johann Gottfried Galle using predictions by Urbain Le Verrier
The inclusion of the works of other, non-British scientists of this era--such as Alexander Von Humboldt, Heinrich Wilhelm Brandes, Joseph Fourier, William Rankine, Matthew Maury, and Urbain Le Verrier
, among many others--would have very nicely filled out the picture of the early years of modern meteorology.
Astronomer Johann Galle found Neptune in 1846 after mathematicians Urbain Le Verrier
and John Couch Adams calculated that an unknown planet could be causing Uranus to speed up and slow down along its orbit (see Page 24).
Johann Galle at Berlin Observatory discovered Neptune in a very deliberate search in 1846, after Urbain Le Verrier
predicted its position from unexplained gravitational tugs on Uranus.
Washington, May 11 ( ANI ): Over 150 years ago, before Neptune was ever sighted in the night sky, French mathematician Urbain Le Verrier
predicted the planet's existence based on small deviations in the motion of Uranus.
1846: German astronomer Johann Galle discovered Neptune, using calculations by Frenchman Urbain le Verrier
based on clues in the orbit of Uranus.
In 1846, the French mathematician Urbain Le Verrier
(1811-1877) spent several months on complex calculations trying to explain the discrepancies between Uranus' observed orbit and the one predicted using Newton's laws of gravity.
In 1846, when Neptune was first observed by telescope, a French publication credited astronomer Urbain Le Verrier
with having earlier predicted the planet's existence.
