The name Asteria is carried by multiple characters in Greek mythology, but judging from her background brief and the planetarium projectors on her knees and headpiece, it is most likely that the intended Asteria is the Titan goddess of the stars and astrology, oracles and prophetic dreams.
Much like Callisto, Asteria provoked the lust of Zeus and was chased by him in an attempt to rape her. Desperate, Asteria transformed herself into a quail but Zeus responded by hunting her down in the form of an eagle. When Asteria found herself cornered, she flung herself into the Aegean Sea still in the form of a quail, where she drowned and became the island of Delos. This island would later be the only piece of earth to give refuge to the fugitive Leto when, pregnant with Zeus's children, she was pursued by vengeful Hera.
Another version of the legend credits Asteria with being the mother of Heracles after being impregnated by Zeus.
