![]() ![]() It is the brightest star in Corona Australis, having an apparent magnitude of 4.102, and an absolute magnitude of 1.11. It is a fast-spinning star, having a rotational velocity of 195 km / 121 mi per second. Meridiana, designated as Alpha Coronae Australis, or Alphekka Meridiana, is an A-type star located at around 125 light-years away from our Solar System. Meridiana is an A-type star, similar to Vega / Alpha Lyrae which is the brightest star in the constellation of Lyra. The brightest star in Corona Australis is Meridiana / Alpha Coronae Australis, which has an apparent magnitude of 4.102. Some of these stars are Alpha (Meridiana) and Beta Coronae Australis, which are the two brightest stars, Epsilon Coronae Australis, which is the brightest example of a W Ursae Majoris variable in the southern sky, the variable stars R and TY Coronae Australis, or Zeta and Gamma Coronae Borealis. There are many interesting stars located in Corona Australis, even though none of them are brighter than magnitude 3.00. Notable Stars in the Constellation of Corona Australis Corona Australis is part of the Hercules family of constellations, along with Aquila, Ara, Centaurus, Corvus, Crux, Cygnus, Hercules, Hydra, Lupus, Lyra, Ophiuchus, Sagitta, Scutum, Sextans, Serpens, Triangulum Australe, and Vulpecula. The constellations surrounding Corona Australis are Ara, Sagittarius, Scorpius, and Telescopium. Its name comes from Latin, and it translates to “the southern crown”, being the southern counterpart of Corona Borealis, the northern crown, which is brighter, and larger. The constellation of Corona Australis is among the smallest constellations in the sky. Since Corona Australis lies alongside the Milky Way, it contains many eye-catching deep-sky objects, such as the dark nebula, known as the Corona Australis Molecular Cloud, which is among the closest star-forming regions to our Solar System, the reflection nebula NGC 6729, the Coronet Cluster, or the globular clusters NGC 6723, and NGC 6541, among many others. ![]() There are many interesting stars located in Corona Australis, even though none of them are brighter than magnitude 3.00. ![]()
