Uranus is the ancient Greek deity of the Heavens, the earliest supreme god. Uranus was the son and mate of Gaia the father of Cronus (Saturn) and of the Cyclopes and Titans (predecessors of the Olympian gods).

Uranus, the first planet discovered in modern times, was discovered by William Herschel while systematically searching the sky with his telescope on March 13, 1781. It had actually been seen many times before but ignored as simply another star (the earliest recorded sighting was in 1690 when John Flamsteed cataloged it as 34 Tauri). Herschel named it “the Georgium Sidus” (the Georgian Planet) in honor of his patron, the infamous (to Americans) King George III of England; others called it “Herschel”. The name “Uranus” was first proposed by Bode in conformity with the other planetary names from classical mythology but didn’t come into common use until 1850.

Uranus has been visited by only one spacecraft, Voyager 2 on Jan 24 1986.

Most of the planets spin on an axis nearly perpendicular to the plane of the ecliptic but Uranus’ axis is almost parallel to the ecliptic. At the time of Voyager 2’s passage, Uranus’ south pole was pointed almost directly at the Sun. This results in the odd fact that Uranus’ polar regions receive more energy input from the Sun than do its equatorial regions. Uranus is nevertheless hotter at its equator than at its poles. The mechanism underlying this is unknown.
