Alpha Centauri is the third brightest star in the night sky. To the naked eye it shines atapparent magnitude-0.27, which is fainter thanCanopus (mag. -0.72)but brighter thanArcturus (mag. -0.04). However, Alpha Centauri is not a single star; it's a triple consisting of two bright compo...
Alpha Centauri, triple star system that contains Proxima Centauri, the closest star to the Sun, about 4.2 light-years distant. The system is the third brightest star in the sky. The nearest extrasolar planets are the three planets that orbit Proxima Cent
Thanks to high-precision absolute radial velocity measurements, it is now robustly established that Proxima Centauri is bound to AB and that it takes 511 kyr to complete a single orbit around the inner binary [1,4]. Hence, the closest stars to Earth belong to a triple stellar system. ...
