Delphinus

Abbreviation: Del
Genitive: Delphini
Right Ascension: 20.70 hours
Declination: 13.81 degrees

Delphinus, the Dolphin, can be seen late summer in the Northern Hemisphere.

Delphinus (the Dolphin) was known by Ancient Greeks as the 'Sacred Fish' and appears twice in mythology, once a dolphin helped Posideon located the mermaid, Amphitrite, and brought her back to be Poseidon's Queen in his golden palace at the bottom of the sea. As a reward Poseidon placed the dolphin among the stars. The second appearance is when Arion, a poet and musician was sailing back to Greece, when his crew turned against him, using a Lyre he summoned up a school of dolphins, throwing himself into the sea; one of the dolphins carried him on its back to Greece.
