CETO
Ceto (; grc, Κητώ, Kētṓ, sea monster) is a primordial sea goddess in Greek mythology, the daughter of Pontus and his mother, Gaia. As a mythological figure, she is considered to be one of the most ancient deities, and bore a host of monstrous children fathered by Phorcys, another child of Gaia and Pontus. The small Solar System body 65489 Ceto was named after her, and its satellite after Phorcys. Ceto was also variously called Crataeis (Κράταιις, ''Krataiis'', froκραταιίς"mighty") and Trienus (Τρίενος, ''Trienos'', froτρίενος"within three years"), and was occasionally conflated by scholars with the goddess Hecate (for whom Crataeis and Trienus are also epithets). This goddess should not be confused with the minor Oceanid also named Ceto, or with various mythological beings referred to as ''ketos'' (plural ''kētē'' or ''ketea''); this is a general term for "sea monster" in Ancient Greek.

65489 Ceto
65489 Ceto, as a binary also (65489) Ceto/Phorcys, is a binary trans-Neptunian object (TNO) discovered on March 22, 2003, by Chad A. Trujillo and Michael Brown at Palomar. It is named after the sea goddess Ceto from Greek mythology. It came to perihelion in 1989. Physical characteristics 65489 Ceto is an example of a close binary TNO system in which the components are of similar size. Combined observations with the infrared Spitzer Space Telescope and the Hubble Space Telescope allow the diameter of Ceto itself to be estimated at and the diameter of Phorcys at , assuming equal albedo for both components. The binary nature of Ceto enables direct calculation of the system mass, allowing estimation of the masses of the components and providing additional constraints on their composition. The estimated density of Ceto is , significantly less than that of the large TNOs (Haumea: 3.0 g/cm3, Eris: 2.26, Pluto: 2.03, Charon: 1.65) but significantly more than that of smaller TN ...
