Uranus

Uranus (or Sol VII) was the seventh planet in the Sol system. It was discovered in 1781 by William Herschel. (PROSE: Neptune) Oberon was one of its moons. (PROSE: GodEngine)

In the late 40th century, Uranus was among the "Big Four" powers in an alliance against the Dalek invasions, when it was decided to found the Space Security Service. (PROSE: The Outlaw Planet) A lengthy mining operation found taranium deposits there, which powered the Daleks' Time Destructor. At this time Uranus was referred to as a "dead planet", implying previous occupation that had ended. (TV: The Daleks' Master Plan)

In 4010, representatives of various races including the Ice Warriors, Pakhars, Alpha Centaurans, and Guermantians, went to Cressida to watch a rare chemical reaction in the atmosphere of Uranus. (PROSE: Uranus)
