On this Day: On March 13, 1781, British astronomer William Herschel used a telescope to survey all stars, down to those about 10 times fainter than those visible to the unaided eye, and made the discovery of Uranus. Within a year, Herschel determined one star was distinctive and had an apparent planetary orbit.
The Greek sky deity Ouranos, the first of the rulers of the heavens, inspired the name Uranus, which became the name given to the planet after about 1850.
In the entire history of space travel, only one spacecraft has ever come quite close to Uranus. On January 24th, 1986, NASA's Voyager 2 made its closest approach to Uranus, passing just 81,000 kilometres from the planet's cloud tops.
The third largest planet in the solar system, Uranus is located seven planets from the sun. Despite being visible to the naked eye, Uranus has long been mistaken for a star due to its low brightness and sluggish orbit. The planet's remarkable tilt, which causes its axis to point almost directly at the sun, is another noteworthy feature.
