Proxima Centauri is an M5 V, similar in color and surface temperature to Betelgeuse, but less evolved and far dimmer because of its far smaller size. Compared to the sun a white dwarf star is. Problem 2. Alpha Centauri B is the second star of the Alpha Centauri System.It has a mass 0.9x that of Sol and a diameter 0.8x that of Sol.. Alpha Centauri Ba 'Innes' Alpha Centauri Ba, officially designated Innes, is the first planet of Alpha Centauri B and the first planet to actually be photographed directly in the Alpha Centauri System. It would only appear as a fifth magnitude star from Alpha Centauri AB despite their proximity. Alpha Centauri (Latinized from α Centauri, abbreviated Alpha Cen or α Cen) is the closest star system and closest planetary system to Earth's Solar System at 4.37 light-years (1.34 parsecs) from the Sun.It is a triple star system, consisting of three stars: α Centauri A (officially Rigil Kentaurus), α Centauri B (officially Toliman), and α Centauri C (officially Proxima Centauri).
