Thyone Template:IPAc-en, also known as Jupiter XXIX, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard in 2001, and given the temporary designation S/2001 J 2.[1][2]
Thyone is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 21,605,000 kilometres in 603.58 days, at an inclination of 147.28° to the ecliptic (146.93° to Jupiter's equator) with an eccentricity of 0.2526. Its average orbital speed is 2.43 km/s.
It was named in August 2003 after Thyone, better known as Semele, mother of Dionysus in Greek mythology.[3]
Thyone belongs to the Ananke group, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 million kilometres, at inclinations of roughly 150°.
