where is the closest binary star system?
Alpha Centauri (α Cen / α Centauri) is the brightest star system in the southern constellation of Centaurus. Although it appears as a single point to the naked eye, Alpha Centauri is actually a system of three stars, one of which is the fourth brightest star in the night sky. The two brightest components of the system are too close to be resolved as separate stars by the naked eye and so are perceived as a single source of light with a total visual magnitude of about −0.27 (brighter than the third brightest star in the night sky, Arcturus). The closest star system to the Sun is the Alpha Centauri system. Of the three stars in the system, the dimmest — called Proxima Centauri — is actually the nearest star. The bright stars Alpha Centauri A and B form a close binary as they are separated by only 23 times the Earth- Sun distance – slightly greater than the distance between Uranus and the Sun.
