The story of the word

William Herschel found it in 1781 and wanted to call it Georgium Sidus after George III, which the rest of Europe declined to accept. Johann Bode proposed Uranus instead, because the genealogy then ran in order: Uranus fathered Saturn, Saturn fathered Jupiter. It is the one planet in the solar system carrying a Greek name rather than a Roman one, and the name only became universal in the 1850s.
