Alpha Centauri A is about the same size and age as our Sun with a spectral type of G2V
Alpha Centauri B is about 14% smaller that our Sun and a lot cooler having a spectral type of K1V
There is a third star, not surprisingly called Alpha Centauri C or Proxima Centauri which is the closest star to Earth.
