Alpha Centauri B is the companion star, or secondary, of the binary system, and is slightly smaller and less luminous than the Sun. It is a main-sequence star of spectral type K1 V, making it more an orange color than the primary star.Alpha Centauri B is about 90% the mass of the Sun and 14% smaller in radius.lpha Centauri (Î± Cen), also known as Rigil Kent (/ËraÉªdÊÉl ËkÉnt/) or Toliman, is the closest star system to the Solar System at 4.37 ly (1.34 pc).
