Dione (moon)

Dione (/daɪˈoʊni/;Greek: Διώνη) is a moon of Saturn. It was discovered by Italian astronomer Giovanni Domenico Cassini in 1684. It is named after the Titaness Dione of Greek mythology. It is also designated Saturn IV.

Name

Giovanni Domenico Cassini named the four moons he discovered (Tethys, Dione, Rhea and Iapetus) Sidera Lodoicea ("the stars of Louis") to honor king Louis XIV. Cassini found Dione in 1684 using a large aerial telescope he set up on the grounds of the Paris Observatory. The satellites of Saturn were not named until 1847, when William Herschel's son John Herschel published Results of Astronomical Observations made at the Cape of Good Hope, suggesting that the names of the Titans (sisters and brothers of Cronus) be used.

Orbit

Dione orbits Saturn with a semimajor axis about 2% less than that of the Moon. However, reflecting Saturn's greater mass, Dione's orbital period is one tenth that of the Moon. Dione is currently in a 1:2 mean-motion orbital resonance with moon Enceladus, completing one orbit of Saturn for every two orbits completed by Enceladus. This resonance maintains Enceladus's orbital eccentricity (0.0047), providing a source of heat for Enceladus's extensive geological activity, which shows up most dramatically in its cryovolcanic geyser-like jets.

Evander (philosopher)

Evander (or Euander) (Greek: Εὔανδρος), born in Phocis or Phocaea, was the pupil and successor of Lacydes, and was joint leader (scholarch) of the Academy at Athens together with Telecles.

In the final ten years of Lacydes' life (c. 215-c. 205), Evander and Telecles had helped run the Academy due to Lacydes being seriously ill. They continued running the Academy after the death of Lacydes, without formally being elected scholarchs. On Telecles' death in 167/6 BC, Evander remained scholarch for a few more years. Evander himself was succeeded by his pupil Hegesinus. Concerning the opinions and writings of this philosopher nothing is known.

Several Pythagoreans of the name of Evander, who were natives of Croton, Metapontum, and Leontini, are mentioned by Iamblichus, and a Cretan Evander occurs in Plutarch.
