Zeta Coronae Australis
What is Zeta Coronae Australis
Zeta Coronae Australis traces the small arc of the Southern Crown, the austral counterpart to Corona Borealis, set beside the bright body of Sagittarius. At 193 light-years, it is a white A-type star, a quiet member of a curving figure that ancient astronomers already recognised —Ptolemy listed it in his Almagest. Its brightness is modest, yet it defines the exact geometry of the half-ring.
