Summary: Alpha Centauri (α Centauri, abbreviated Alpha Cen, α Cen) is the closest star system to the Solar System at a distance of 4.37 light-years (1.34 pc). It consists of three stars: the pair Alpha Centauri A (also named Rigil Kentaurus) and Alpha Centauri B together with a small and faint red dwarf, Alpha Centauri C (also named Proxima Centauri), that may be gravitationally bound to the other two.
Summary: The sun's closest stellar neighbors are three stars in the Alpha Centauri system. The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. The third star is Proxima Centauri.
**Alpha Centauri** (**α Centauri**, abbreviated **Alpha Cen**, **α Cen**) is the [closest](https://en.wikipedia.org/wiki/List_of_nearest_stars_and_brown_dwarfs "List of nearest stars and brown dwarfs") [star system](https://en.wikipedia.org/wiki/Star_system "Star system") to the [Solar System](https://en.wikipedia.org/wiki/Solar_System "Solar System") at a distance of 4.37 [light-years](https://en.wikipedia.org/wiki/Light-year "Light-year") (1.34 [pc](https://en.wikipedia.org/wiki/Parsec "Parsec")). It consists of three stars: the [pair](https://en.wikipedia.org/wiki/Binary_star "Binary star") **Alpha Centauri A** (also named **Rigil Kentaurus**) and **Alpha Centauri B** together with a small and faint [red dwarf](https://en.wikipedia.org/wiki/Red_dwarf "Red dwarf"), **Alpha Centauri C** (also named **[Proxima Centauri](https://en.wikipedia.org/wiki/Proxima_Centauri "Proxima Centauri")**), that may be gravitationally bound to the other two. To the unaided eye, the two main components appear as a single point of light with an apparent [visual magnitude](https://en.wikipedia.org/wiki/Visual_magnitude "Visual magnitude") of 0.27, forming the brightest [star](https://en.wikipedia.org/wiki/Star "Star") in the southern [constellation](https://en.wikipedia.org/wiki/Constellation "Constellation") of [Centaurus](https://en.wikipedia.org/wiki/Centaurus "Centaurus") and the [third-brightest](https://en.wikipedia.org/wiki/List_of_brightest_stars "List of brightest stars") star in the night sky, outshone only by [Sirius](https://en.wikipedia.org/wiki/Sirius "Sirius") and [Canopus](https://en.wikipedia.org/wiki/Canopus "Canopus").
