Ara (pronounced /ˈɑːrə/, Latin: altar) is a southern constellation situated between the constellations Scorpius and Triangulum Australe.
Contents |
Ara's brightest star, β Arae, has an apparent magnitude of 2.9. γ Arae is a double star just south of β. μ Arae is believed to have at least four planets orbiting it, one of which may be rocky in nature.
The northwest corner of Ara is crossed by the Milky Way and contains several open clusters and diffuse nebulae. The brightest of the globular clusters, NGC 6397, is 8,200 light-years from our solar system and may be the closest cluster of that kind.
This constellation was one of Ptolemy's original 48 constellations.
The altar, usually depicted upside down, but sometimes upright with the smoke drifting into the Milky Way, was identified as that of the centaur Chiron; its original Latin name was Ara Centauri. It was also occasionally called the altar of Dionysus.
