Chaldene /kælˈdn/, also known as Jupiter XXI, is a retrograde irregular satelliteofJupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, in 2000, and given the temporary designation S/2000 J 10.[5][1][6]

Chaldene is about 3.8 kilometres in diameter, and orbits Jupiter at an average distance of 22,713,000 km in 759.88 days, at an inclination of 167° to the ecliptic (169° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2916.

It was named in October 2002 after Chaldene, the mother of SolymosbyZeusinGreek mythology.[7]

It belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm and at an inclination of about 165°.
