Alpha+Centauri+1A

=__Alpha Centauri__ Alpha Centauri is said to be a steller star that is located very close to the sun. To be exact, 4.35 light years away. It's also said to be a triple-star system. The close, first two stars form a binary. Centauri A appears to be yellow due to the fact that the sun is a G2 and as is Centauri A. Because of that, The sun and Centauri A appears to be almost the same size and said to be identical temperature. Centauri B is a mild orange color with a spectral type called K1. Now while both Centauri A/B are said to be very alike, Proxima appears to be a dim, red Dwarf with the spectral type M5. Proxima was so faint that astronomers didn't find it until 1915. It was discovered by Robert Thorburn Aynton Innes while he was making observations. Centauri A/B are about 11 to 35 AU's away and takes just about 80 years to orbit each other. Proxima is just about 13'000 AU's away from Centauri A/B. The age of Proxima is unknown, it is said that M-class stars live for billions of years,Nevertheless proxima is a flare star. This could only mean that it's only a billion years old, but if it was formed with Centauri A/B, then that means it's about 5 billions years old(just like our universe).=
