Libra (The Balance) Constellation

Libra (pronounced ˈlaɪbrə, ˈliː-) is the Latin name of a large constellation (in fact it extends itself for about 34 degrees across the sky) situated close to the celestial equator. As such, it is at least partly visible from both hemispheres in certain times of the year.

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

The Latin genitive of the constellation name is "Librae" (pronounced ˈlaɪbriː) 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 Librae (the brightest star of Libra based on the Bayer catalog); or 23 Librae (the 23th star in the constellation of Libra based on the Flamsteed catalog).

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