In Greek mythology, Asteria or Asterie is a daughter of the Titans Coeus (Polus) and Phoebe and the sister of Leto. According to Hesiod, by the Titan Perses she had a single child, a daughter named Hecate, the goddess of witchcraft. Other authors made Asteria the mother of the fourth Heracles and Hecate by Zeus.

In ancient Greek religion and mythology, Phoebe was one of the first generation of Titans, who were one set of sons and daughters of Uranus and Gaia. She was the grandmother of Apollo and Artemis, and the witchcraft goddess Hecate. According to myth, she was the original owner of the site of the Oracle of Delphi before gifting it to her grandson Apollo. Her name, meaning "bright", was also given to a number of lunar goddesses like Artemis and later the Roman goddesses Luna and Diana, but Phoebe herself was not actively treated as a moon goddess in her own right in ancient mythology.
