A constellation in the northern sky shaped like a dolphin, located near the celestial equator and visible during summer nights.
From Latin 'delphinus' meaning dolphin, derived from Greek 'delphis.' The constellation was named by ancient astronomers who recognized the dolphin shape in its star pattern.
Ancient sailors used Delphinus to navigate at night because its distinctive four bright stars form a clear diamond shape—one of the few constellations that actually looks like what it's named after, making it a reliable celestial landmark.
