The ancients looked to the heavens for guidance and the origins of universal truths. Stars of ancient mythology live on as the stars in our evening sky. Many of the Roman and Greek gods and heroes are immortalized in the names of our most visible stellar bodies; these celestial names make for unique, cosmic names for dogs.

Cosmic Dog Names From Stellar Bodies With Greek Names

  • Andromeda: The nearest large galaxy to our own, the Milky Way. Andromeda is named for the daughter of Ethiopian King Cepheus and his wife Cassiopeia. In the Greek myth, Cassiopeia vainly brags that her daughter is more beautiful than any of Poseidon’s daughters, the Nereids. Outraged by the insult to his daughters, Poseidon sends the sea monster, Cetus, to ravage the coast of Ethiopia. The only remedy to assuage Poseidon’s ruffled feathers is to chain the king’s daughter, Andromeda, to a rock and sacrifice her to the sea monster. Happily, Perseus happens to fly by on his winged sandals, just as Cetus is preparing to devour the young beauty. Perseus swiftly slays the sea monster and claims Andromeda as his bride. The descendants of Perseus and Andromeda are known today as the Persians.
  • Anthe: A small moon of Saturn, Anthe is named for one of the Alkyonides. In the Greek myth, the Alkyonides were nymph daughters of the king of the giants, Alkyoneus.
