The closest #star system to the Sun is the Alpha #Centauri system.

Of the three #stars in the system, the dimmest -- called #Proxima Centauri -- is actually the nearest star.

The bright stars Alpha Centauri A and B form a close #binary as they are separated by only 23 times the Earth- Sun distance - slightly greater than the distance between Uranus and the Sun.
