Persephone and Dionysos. Roman copy after a Greek original of the 4th–3rd century B.C. Marble. Hermitage.. In ancient Greek mythology and religion, Persephone (/ p ər ˈ s ɛ f ə n iː / pər-SEF-ə-nee; Greek: Περσεφόνη, romanized: Persephónē, classical pronunciation: [per.se.pʰó.nɛː]), also called Kore (/ ˈ k ɔːr iː / KOR-ee; Greek: Κόρη, romanized: Kórē, lit.
The IAU's names for exoplanets – and on most occasions their host stars – are chosen by the Executive Committee Working Group (ECWG) on Public Naming of Planets and Planetary Satellites, a group working parallel with the Working Group on Star Names (WGSN). [1] Proper names of stars chosen by the ECWG are explicitly recognised by the WGSN. [1]
Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [4] [2] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
According to the novel, Persephone is the tenth planet (a Planet X) of the Solar System. While actually proposed in the 1970s to account for perturbations for the orbit of Neptune , Niven gives it additional qualities such as retrograde motion , an orbit tilted 61 degrees to the ecliptic , and a mass slightly less than that of Saturn .

Persephone is depicted as goddess of life in Sacrifice; In Elite: Dangerous, Persephone is the name given to the game's fictional depiction of the hypothetical Planet Nine in the Sol system, a world made largely of ice but with no atmosphere. In Skylanders, Persephone gives Skylanders upgrades in exchange for gold and is the most powerful fairy.
Initially, the names given to minor planets followed the same pattern as the other planets: names from Greek or Roman myths, with a preference for female names. With the discovery in 1898 of the first body found to cross the orbit of Mars, a different choice was deemed appropriate, and 433 Eros was chosen.
