Ara (The Altar) Constellation

Ara (pronounced ˈɛərə) is the Latin name of a constellation situated south of the celestial equator. As such, it is more easily visible from the southern hemisphere.

In English language this constellation is also known as "The Altar" while in astronomical texts and literature this constellation is often abbreviated as "Ara" (according to the standard of the International Astronomical Union - IAU) or as "Arae" (according to a naming convention used by NASA).

The Latin genitive of the constellation name is "Arae" (pronounced ˈɛəriː) and it is used to identify some of the brightest stars in this constellation based on the Bayer or Flamsteed star naming convention. For instance: α Arae (the brightest star of Ara based on the Bayer catalog); or 23 Arae (the 23th star in the constellation of Ara based on the Flamsteed catalog).

Ara is below the horizon from Greenwich, United Kingdom [change].
