Sirius is the brightest star in Earth’s night sky and is located in the constellation Canis Major, earning its nickname "the Dog Star." The system consists of two stars: Sirius A, a luminous main-sequence star, and Sirius B, a faint white dwarf companion. Sirius is about 8.6 light-years away from Earth and has been revered in cultures since ancient times for its remarkable brightness and distinct appearance.

The Seestar only sees Sirius as a single bright star.
