Alpha Centauri is a binary star system with two stars ("A" and "B") nearly the same mass as the sun. Alpha Centuri A is 1.1 times the mass of the sun (bigger), while Alpha Centuri B is 0.9 times the mass of the sun (smaller).

Is alpha centauri the farthest star from the earth?
No; in fact, the Alpha Centauri system is the closest star system to Earth.The closest star to us is the Sun; the next-closest star is Proxima Centauri, part of the Alpha Centauri system.
What is the third star from the sun?
The third closest star will be either Alpha Centauri A or Alpha Centauri B depending on the time of observation.
What is the closest star near to the sun?
Alpha Centauri
What is the closest star to our Sun?
Proxima Centauri is the closest star to our sun-- but it's neighbor, Alpha Centauri, is nearly the same distance.
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.

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 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.
What is the closest star besides sun?
The Alpha Centauri system.
Is Alpha-Centauri the closest star to the Sun?
Alpha Centauri is the second-closest, at 4.5 Light Years away. The closest star is Proxima Centauri, which is 4.2 light years distant. However, Alpha Centauri is a star very much like our Sun, while Proxima Centauri is a very dim dwarf star, hardly visible from Earth even though it is closest.
