22 de sept. de 2021 · On the night of Sept. 23-24, 1846, astronomers discovered Neptune, the eighth planet orbiting around the Sun. The discovery was made based on mathematical calculations of its predicted position due to observed perturbations in the orbit of the planet Uranus.

There is evidence that Neptune was seen and recorded by Galileo Galilei in 1613, Jérôme Lalande in 1795, and John Herschel in 1830, but none are known to have recognized it as a planet at the time. [6] These pre-discovery observations were important in accurately determining the orbit of Neptune.
Hace 1 día · Neptune was discovered on September 23, 1846. It is the second planet to be found using a telescope. Although Johann Gottfried Galle and Heinrich Louis d’Arrest have the distinction of having been the first individuals to identify Neptune in the night sky, credit for its “discovery” was eventually credited to John Couch Adams ...
Neptune's largest moon Triton was discovered on Oct. 10, 1846, by William Lassell, just 17 days after Johann Gottfried Galle discovered the planet. Since Neptune was named for the Roman god of the sea, its moons are named for various lesser sea gods and nymphs in Greek mythology.
The discovery of Neptune finally laid Bode’s law to rest. Instead of being near the predicted 38.8 AU, Neptune was found to be only 30.1 AU from the Sun. This discrepancy, combined with the lack of any scientific explanation as to why the law should work, discredited it.
24 de sept. de 2021 · NASA. Sep 24, 2021. Image Article. On the night 175 years ago on Sept. 23-24, 1846, astronomers discovered Neptune, the eighth planet orbiting our Sun. The discovery was made based on mathematical calculations of its predicted position due to observed perturbations in the orbit of the planet Uranus.
Neptune was the first planet located through mathematical calculations. Using predictions sent to him by French astronomer Urbain Le Verrier, based on disturbances in the orbit of Uranus, German astronomer Johann Galle was the first to observe the planet in 1846.
