"Alpha Centauri" is getting the boot. The longstanding star name has been displaced by its ancient counterpart in a new International Astronomical Union (IAU) catalog that designates 227 official names for different stars in the sky. The move was intended to reduce confusion, according to the IAU.
How did Alpha Centauri A get its name?
They're all stars that changed their names. But Alpha Centauri, our nearest star system, is taking back its ancient moniker, Rigil Kentaurus, which means “foot of the centaur” in Arabic.
Why is Rigil Kentaurus also known as Alpha Centauri?
Rigel Kentaurus is the third-brightest star in the night sky. However, 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.
