Science is unable to know for sure if there is life on the planets surrounding Alpha Centauri. However, it has been identified as one of the environments likely most similar to earth's environment.

Alpha Centauri is a binary star system, andpossibly a triple star system.

Alpha Centauri A is a G2V star similar to our own Sun.
Alpha Centauri B is a K1V star
Alpha Centauri C (Proxima Centauri) is a M5 star.

A will end it's life, similar to our Sun, by first expanding as a red giant and them shed it's our layers before becoming a white dwarf.
B will end it's life the same as above.
C will end it's life, eventually, after about four trillion years, by just fading away.

However, there is a possible chance that if B becomes a white dwarf before A, then it might be able to accrete mass from A and become a nova.

Dating the demise of a star is very difficult. We know that Alpha Centauri A is very similar to our own Sun - albeit a bit larger - and they formed around the same time, so A will probably end it's life a little earlier than our own Sun (Approximately 4 billion years time). Alpha Centauri B is a much cooler star than A, so will probably out live it.

However, because they are a binary pair and their close approach to each other (11 AU) it is possible that when A becomes a white dwarf, it may be able to accrete hydrogen off of B to produce a nova explosion. However, because of the highly eccentric orbit, this seems unlikely.

In that case B will continue as a orange dwarf for billions more years.

What is the difference between Alpha Centauri A and Alpha Centauri B?

Alpha Centauri is a binary star system, commonly known as Alpha Centauri ABAlpha Centauri A is about the same size and age as our Sun with a spectral type of G2VAlpha Centauri B is about 14% smaller that our Sun and a lot cooler having a spectral type of K1VThere is a third star, not surprisingly called Alpha Centauri C or Proxima Centauri which is the closest star to Earth.See related link for more information.


What type of star is alpha centari?

Alpha Centauri (Rigil Kentaurus, Rigil Kent, or Toliman) is a binary star systemAlpha Centauri A is a G2 star or yellow dwarf - very similar to our own SunAlpha Centauri B is a K1 star or orange dwarf.and possibly a triple star system.Alpha Centauri C (Proxima Centauri) is a M5 star or red dwarfAlpha Centauri (Rigil Kentaurus) is the brightest star in the southern constellation of Centaurus. Although it appears to us as a single object, Alpha Centauri is actually a binary star system.Alpha Centauri A has a spectral type of G2V - so it is a yellow dwarf.Alpha Centauri B has a spectral type of G2V - so it is an orange dwarf.

What is the second star in the alpha centauri star system?

Alpha Centauri, although it appears to the naked eye as a single star, is a binary pair. Together they are designated Alpha Centauri AB, the more massive and luminous in the pair designated Alpha Centauri A, the less massive and luminous Alpha Centauri B. Together, this pair is the third brightest "star" in the night sky. There is a third star probably interacting gravitationally with the pair, Proxima Centauri, also designated Alpha Centauri C, a red dwarf which is not visible to the naked eye but is the next closest star to our Sun. Alpha Centauri B has about 90% of the mass of our Sun and is about 45% as bright. Note that Alpha Centauri B is not the "second" star (second brightest) in the constellation Centaurus: that is Beta Centauri, which is itself a trinary star system.

Why does Alpha Centauri appear to be yellow-white?

Alpha Centauri A (Rigil Kentaurus) is a type G2V star - which is the same as our Sun so it has a colour of yellow.Alpha Centauri is abinary star system.Alpha Centauri A - the primary star, is a G2V star so has the apparent colour of yellowish-white, the same as our Sun.Alpha Centauri B - the secondary star, is a K1V star so has the apparent colour of yellow-orange.
