Thyone, also known as Jupiter XXIX, is another one of Jupiter's moons. It is a member of the Ananke group, which is a group of small moons that orbit Jupiter in a retrograde direction. Retrograde means that they orbit Jupiter in the opposite direction of Jupiter's rotation. Thyone was discovered in 2001 by astronomers Brett J. Gladman, John J. Kavelaars, et al., using observations from the Canada-France-Hawaii Telescope.
Here are some key points about Thyone:
Size and Characteristics: Like many of Jupiter's smaller moons, Thyone is relatively small and has an irregular shape. Its size and composition are similar to other moons in the Ananke group.
Orbit: Thyone follows a retrograde, irregular orbit around Jupiter. Its orbit is relatively distant from the planet and is tilted with respect to Jupiter's equator.
Name Origin: Thyone is named after a figure from Greek mythology. In Greek mythology, Thyone was a name sometimes associated with Semele, who was the mother of Dionysus, the god of wine and revelry.
Exploration: As of my last knowledge update in September 2021, there haven't been any dedicated space missions to study Thyone specifically. Most of the information about this moon and others in its group comes from observations made by telescopes and spacecraft like the Galileo orbiter.
