Gamma Delphinus
From Tardis Wiki, the free Doctor Who reference
Gamma Delphinius was a double star; Gamma1 Delphinius and Gamma2 Delphinius were both G Class stars.[source needed] The system was located in space controlled by Earth and its allied planets. Gamma Delphinus had at least four planets; at least one of them, Gamma Delphinius IV, was home to an Earth colony in the 26th century. (PROSE: Sanctuary)
Behind the scenes
There exists a real-world binary star called Gamma Delphini; it is a binary star in the Delphinus constellation, very close to the celestial equator, about a hundred one light-years from Earth. Its components, Gamma1 Delphini and Gamma2 Delphini, are, respectively, an F Class star (brighter and hotter than Earth's Sun) and a K Class star (dimmer and redder than Earth's Sun).
