Ananke is a retrograde irregular moon of Jupiter. It was discovered by Seth Barnes Nicholson at Mount Wilson Observatory in 1951 and is named after the Greek mythological Ananke, the personification of necessity, and the mother of the Moirai (Fates) by Zeus. The adjectival form of the name is Anankean.

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.
The Pasiphae group is a group of retrograde irregular satellites of Jupiter that follow similar orbits to Pasiphae and are thought to have a common origin.
Jupiter LII, originally known as S/2010 J 2, is a natural satellite of Jupiter. It was discovered by Christian Veillet in 2010. It received its permanent number in March 2015. It takes 1.69 years to orbit around Jupiter, and its average distance is 21.01 million km. Jupiter LII has a diameter of about 1 kilometer and in 2010 it was labeled the smallest known moon in the Solar System to have been discovered from Earth. It is a member of the Ananke group. With an estimated diameter of 1 km (0.62 mi), Jupiter LII is one of the smallest known moons of Jupiter.
The following outline is provided as an overview of and topical guide to Jupiter:
Jupiter LIV, originally known as S/2016 J 1, is an outer natural satellite of Jupiter. It was discovered by Scott S. Sheppard in 2016, but not announced until June 2, 2017 via a Minor Planet Electronic Circular from the Minor Planet Center. It is about 1 kilometer in diameter and orbits at a semi-major axis of about 20,650,845 km with an inclination of about 139.8°. It belongs to the Ananke group.
Jupiter LXVIII, provisionally known as S/2017 J 7, is an outer natural satellite of Jupiter. It was discovered by Scott S. Sheppard and his team in 2017, but not announced until July 17, 2018, via a Minor Planet Electronic Circular from the Minor Planet Center. It is about 2 kilometers in diameter and orbits at a semi-major axis of about 20,627,000 km with an inclination of about 143.4°. It belongs to the Ananke group.
Jupiter LXX, originally known as S/2017 J 9, is an outer natural satellite of Jupiter. It was discovered by Scott S. Sheppard and his team in 2017, but not announced until July 17, 2018, via a Minor Planet Electronic Circular from the Minor Planet Center. It is about 3 kilometers in diameter and orbits at a semi-major axis of about 21,487,000 km with an inclination of about 152.7°. It belongs to the Ananke group.
S/2021 J 1 is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard on 12 August 2021, using the 6.5-meter Magellan-Baade Telescope at Las Campanas Observatory, Chile. It was announced by the Minor Planet Center on 5 January 2023, after observations were collected over a long enough time span to confirm the satellite's orbit.
