The Sirius System, known colloquially as the "Dog Star", is an inhabited binary star system located 8.6 light-years from the Solar System in the constellation Canis Major. The system, home to the brightest star in Earth's night sky, is largely inhabited by the Starlight Church, a sect of Atenism, who live in several stations orbiting the two central stars. The Starlight Church hold Sirius with a special reverence due to its brightness, and they worship it as the utmost divine cosmological entity. The system is a backwater with few other residents aside from some miners in the system's outer reaches.

Star[edit | edit source]

Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The distance between the two varies between 8.2 and 31.5 astronomical units as they orbit every 50 years. Many cultures have historically attached special significance to Sirius, particularly in relation to dogs. It is often colloquially called the "Dog Star" as the brightest star of Canis Major, the "Great Dog" constellation. The heliacal rising of Sirius marked the flooding of the Nile in Ancient Egypt and the "dog days" of summer for the ancient Greeks, while to the Polynesians, mostly in Earth's Southern Hemisphere, the star marked winter and was an important reference for their navigation around the Pacific Ocean.
