Alpha Centauri System

The nearest star system to the Sun. Contains a star a little bigger than the Sun and a star a little smaller orbiting each other, as well as a distant Red Dwarf companion Proxima Centauri that may or may not be orbiting the other two. No exoplanets have been found yet, although intense research to find them has been undertaken.
