Ananke Group
The Ananke group is a group of retrograde irregular satellites of Jupiter that follow similar orbits to Ananke and are thought to have a common origin. Their semi-major axes (distances from Jupiter) range between 19.2 and 21.8 Gm, their orbital inclinations between 144.3° and 155.5°, and their orbital eccentricities between 0.09 and 0.30. The members of the Ananke group are: The International Astronomical Union (IAU) reserves names ending in -e for all retrograde moons, including this group's members. Origin The Ananke group is believed to have been formed when an asteroid An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids).
