The planet boasts a ring system and 28 known satellites. William Herschel discovered Uranus on 13 March 1781, although he thought it was a comet for some time. Later, it was realized that it was observed several times by others, but, not recognized as a planet. It is just barely visible in a dark sky. Uranus is unique in that the polar axis is tilted some 97° to it's orbit. Uranus in Orbiter Uranus has been a part of Orbiter since the beginning with the release of Orbiter 2001. In Orbiter 2002, the orbital parameters of Uranus was moved to Vsop87.dll. The add-on uranus.zip included storm patterns on the Uranus visuals.
