Thyone (moon)
From Free net encyclopedia
Thyone (thye-oe'-nee, Template:IPA2; Greek Θυώνη), or Jupiter XXIX, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, et al. in 2001, and given the temporary designation S/2001 J 2. Thyone is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 21,406 Mm in 639.803 days, at an inclination of 147° to the ecliptic (116° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2526.
Its name comes from Thyone, better known as Semele, one of Zeus' conquests in Greek mythology.
Thyone belongs to the Ananke group, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 Gm, at inclinations of roughly 150°.
