Notable features

Stars

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.[citation needed]

The constellation's stars have no names in Western culture, but the Chinese call α Arae "Choo" ("club" or "staff"), and ε Arae "Tso Kang", meaning 'left guard'.[citation needed]

Deep sky objects

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 (7.8×1016 km) from our solar system and might be the closest cluster of that kind.[citation needed]
