Legend of the Constellation

Delphinus is the dolphin that persuaded Amphitrite, a nereid that she should accept Poseidon`s wooing. Amphitrite had wanted to keep her virginity thus running off. Delphinus was one of those tasked with finding her. Another story has Delphinus as the dolphin who saved the Greek poet Arion of Lesbos from drowning after he was thrown overboard.

There are no major meteor showers that radiate from within this constellation.

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
