Asteroid 14792, Thyestes, was discovered on September 24, 1973 by C. J. van Houten and Ingrid van Houten-Groeneveld on photographic plates taken by Tom Gehrels at Palomar Observatory near Pauma Valley, California. It has a period of 11 years, 256 days.
Thyestes was the son of Pelops, grandson of the notorious sinner Tantalus, and brother of Atreus, with whom he fought for the throne of Mycenae after they were both banished from Olympia for murdering their half-brother Chrysippus. Atreus killed two of Thyestes' children and gave them to Thyestes to eat, taunting him with the dead boys' severed hands and feet, as revenge for Thyestes' affair with Atreus' wife Aerope. Because of this Thyestes cursed the family of Atreus with a horrific curse that was only lifted when Atreus' grandson Orestes worked out the evil afflicting his family by avenging the murder of his father Agamemnon by Thyestes' son Aegisthus and Clytemnestra, Agamemnon's wife and Orestes' mother by killing Clytemnestra and suffering persecution by the Furies until he was finally exonerated by the gods.
Astrologically,asteroid Thyestes seems to indicate scheming for power, being ruthless and paying for it.
