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).
