Sextuple Star System • Castor is not just one star but a complex sextuple star system, consisting of three binary pairs orbiting a common center. • 2. Main Components • The main visible components, Castor A and Castor B, are both spectroscopic binaries, meaning each is a pair of stars orbiting closely together. • 3. Location • Castor is located in the constellation Gemini and is one of the two brightest stars in the constellation, the other being Pollux. • 4. Magnitude • The combined apparent magnitude of Castor is about 1.58, making it one of the brighter stars in the night sky. • 5. Distance from Earth • Castor is approximately 51 light-years away from Earth. • 6. Castor C • The third pair of stars in the system, known as Castor C or YY Geminorum, are red dwarf stars and are much fainter than Castor A and B. • 7. First Identified as Binary • Castor was first identified as a binary star by the English astronomer James Bradley in 1719. • 8. Spectral Types • Castor A and B are A-type main-sequence stars, while Castor C (YY Geminorum) consists of two M-type red dwarfs. • 9. Proper Motion • Castor has a high proper motion, moving across the sky at a significant rate relative to the background stars, a sign of its relatively close distance to Earth. • 10. Mythological Significance • In Greek mythology, Castor is one of the twin brothers (along with Pollux) who are represented by the constellation Gemini. Castor and Pollux were known as the Dioscuri.
