Serpens (The Snake) Constellation

Serpens (pronounced ˈsɜːrpɛnz) is the Latin name of a large constellation (in fact it extends itself for about 69 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 Snake" while in astronomical texts and literature this constellation is often abbreviated as "Ser" (according to the standard of the International Astronomical Union - IAU) or as "Serp" (according to a naming convention used by NASA).

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

Serpens is above the horizon from Greenwich, United Kingdom [change]. Altitude: 16°.
