Hercules (The Hercules) Constellation

Hercules (pronounced ˈhɜːrkjʊliːz) is the Latin name of a large constellation (in fact it extends itself for about 57 degrees across the sky) situated north of the celestial equator. As such, it is more easily visible from the northern hemisphere.

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

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

Hercules is above the horizon from Greenwich, United Kingdom [change]. Altitude: 1°.
