This diagram compares the orbital elements and relative sizes of the known members of the Ananke group as of April 2026. The horizontal axis illustrates their average distance from Jupiter, the vertical axis their orbital inclination, and the circles their relative sizes. 107 irregular moons of Jupiter plotted by semi-major axis and inclination as of April 2026. The Ananke group is shown as a tight cluster of yellow-colored points on the left.
The Ananke group (or family or cluster) is a group of retrograde irregular satellites of Jupiter that follow similar orbits to Ananke and are thought to have a common origin.
