Delphinus is a noun that refers to a small constellation in the northern sky, also known as the Dolphin. The term originates from the Latin word "delphinus," meaning "dolphin." In astronomy, it is one of the 88 recognized modern constellations, representing a dolphin leaping out of the water. Delphinus is located in the region of the celestial equator, surrounded by other constellations such as Aquarius, Equuleus, Pegasus, and Sagitta.
The Delphinus constellation is most easily recognizable by its distinctive diamond-shaped pattern of stars, resembling the outline of a leaping dolphin. One of its notable features is the star system Alpha Delphini, which consists of two main stars orbiting each other. These two stars periodically eclipse each other, causing their combined brightness to fluctuate. This variability makes Alpha Delphini an important binary system for studying stellar astrophysics.
Delphinus has been recognized by different civilizations throughout history, including ancient Greeks and Romans. It is associated with various myths and legends, such as the story of a dolphin saving the life of the Greek poet Arion. Since Delphinus is easily visible in the night sky and has a distinctive shape, it has served as a navigational reference for sailors in the past.

The word "delphinus" originates from Latin and is derived from the Greek word "delphīs" (δέλφις). This Greek word itself came from the earlier Greek word "delphús" (δελφύς), which means "dolphin". The exact origin of the Greek word is uncertain, but it is believed to have roots in the Phoenician language, an ancient Semitic language spoken in the Eastern Mediterranean region. In Phoenician, the word for "dolphin" is thought to be "dalfin". Over time, the Greek version "delphīs" was borrowed into Latin as "delphinus", which eventually gave rise to the English word "dolphin".
