Did Galileo Discover Neptune?
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. These pre-discovery observations were important in accurately determining the orbit of Neptune.
How was Neptune discovered?
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.
Who first visited Neptune?
Neptune was supposedly discovered in 1846 by Johann Gottfried Galle using calculations by Urbain Le Verrier and John Couch Adams, making it a joint British-French-German discovery. But these astronomers were not the first to observe Neptune. That honor goes to the famous Italian astronomer Galileo Galilei.

Why did Uranus get its name?
Ultimately, German astronomer Johann Elert Bode (whose observations helped to establish the new object as a planet) named Uranus after an ancient Greek god of the sky. (Uranus is also the only planet to be named after a Greek god rather than a Roman one.)
How did Earth get its name?
The name “Earth” is derived from both English and German words, ‘eor(th)e/ertha’ and ‘erde’, respectively, which mean ground. One interesting fact about its name: Earth is the only planet that wasn’t named after a Greek or Roman god or goddess.

Is star hotter than Sun?
The sun’s surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit). That is why it is red — red stars are cooler than the sun, blue-white stars are hotter. Betelgeuse is, however, much bigger and brighter.
