Alpha Centauri and Surroundings Rigil Kentaurus is the third brightest star in the night sky, though its brightness is due to the proximity of the system — commonly known as Alpha Centauri — which is the sun's closest neighbor, about 4.3 light-years away from Earth. The star is located in the Centaurus constellation, and has an apparent magnitude of -0.27 and an absolute magnitude of 4.4. [See our facts about Rigel Kentaurus.]
