μ Coronae Australis, Latinized as Mu Coronae Australis, is a solitary star located in the southern constellation of Corona Australis. It is a yellow-hued star and is visible to the naked eye with an apparent visual magnitude of 5.217. Parallax measurements put it at a distance of approximately 387 light-years from the Sun, but it is drifting closer with a radial velocity of −16 km/s. It has an absolute magnitude of -0.37.
This object is an aging G-type giant star with a stellar classification of G5-6III. It is roughly 361 million years old with 3.065 times the mass of the Sun. Having exhausted the supply of hydrogen at its core, the star has cooled and expanded away from the main sequence. At present it has 11 times the girth of the Sun. The star is radiating 111 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 5,557 K.
