Which Titan was the father of the stars and planets?

Astraeus was the Titan regarded in Greek mythology as the father of the stars and planets’ visible celestial family. His name comes from the Greek word for “star,” and his mythology is closely tied to the night sky and twilight.

Astraeus was the son of Crius and Eurybia and the consort of Eos, the goddess of dawn. Their union symbolically joins the darkness before dawn with the first light of day. In Hesiod’s Theogony, their children include the winds, the star-bringer Eosphorus, and the stars themselves. Later writers add Eurus, the east wind, to the family.

The question’s wording is a simplified summary of this genealogy rather than a claim that Astraeus created every astronomical body in a modern scientific sense. Ancient Greek myths often personified natural phenomena through divine family relationships.

Crius, Coeus, and Hyperion are easy alternatives because all are Titans with cosmic associations. Crius is Astraeus’s father; Coeus is linked with the heavenly axis and intellect; Hyperion is associated with heavenly light and is the father of the Sun, Moon, and Dawn in another major lineage.
