70 Virginis b

70 Virginis b was a colony planet with an orbiting space station, Dunlop Station.

In 2133, the Eleventh Doctor briefly visited Dunlop Station in 2133, with Rory Williams, while attempting to get back to London, 1814 to retrieve Amy. (COMIC: The Doctor and the Nurse)

Behind the scenes
In the real world, 70 Virginis b is a gas giant about 7.5 times the mass of Jupiter. Discovered in 1996, it orbits, one of the first stars confirmed to have planets in orbit.

At the time The Doctor and the Nurse was published, 70 Virginis b was believed to be within the star system's habitable zone, like Earth, and so was nicknamed "Goldilocks". Later discoveries about the planet's orbit disproved this.
