Gamma Coronae Australis
Binary systemWhat is Gamma Coronae Australis
Gamma Coronae Australis is one of the most beautiful visual binaries in the southern sky: two near-twin yellow-white stars orbiting each other in a dance with a period of around 120 years. Through a modest telescope they part like two pearls of equal size. At just 58 light years away, they are close neighbours in the small Southern Crown, the crown fallen at the feet of Sagittarius.
Where it is and when to see it
Gamma Coronae Australis lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.
