Delphinus (The Dolphin) Constellation
Delphinus (pronounced dɛlˈfaɪnəs) is the Latin name of a constellation 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 Dolphin" while in astronomical texts and literature this constellation is often abbreviated as "Del" (according to the standard of the International Astronomical Union - IAU) or as "Dlph" (according to a naming convention used by NASA).
The Latin genitive of the constellation name is "Delphini" (pronounced dɛlˈfaɪnaɪ) 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 Delphini (the brightest star of Delphinus based on the Bayer catalog); or 23 Delphini (the 23th star in the constellation of Delphinus based on the Flamsteed catalog).
