The quadruple-star system hiding behind a single point of light
In short: Capella is often perceived as a lone star, but it is actually a complex celestial neighborhood. This video explores the system's composition and how to locate it within the Auriga constellation.
While it appears as a single point of light, Capella is a quadruple-star system. It consists of two G-type giant stars orbiting each other every 104 days, accompanied by two red dwarf star companions. It is the brightest star in the constellation Auriga and ranks as the sixth brightest star in the entire night sky.
Located approximately 42.2 light-years from Earth, Capella has an apparent visual magnitude of 0.08. The name is derived from the Latin for "She-Goat" or "Charioteer," reflecting its historical significance in celestial navigation and mythology.
