Sagittarius (The Archer) Constellation

Sagittarius (pronounced sædʒɪˈtɛəriəs) is the Latin name of a large constellation (in fact it extends itself for about 46 degrees across the sky) 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 Archer" while in astronomical texts and literature this constellation is often abbreviated as "Sgr" (according to the standard of the International Astronomical Union - IAU) or as "Sgtr" (according to a naming convention used by NASA).

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

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