Chaldene (moon)

Chaldene or Jupiter XXI, is a non-spherical moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, et al. in 2000, and given the designation S/2000 J 10.[1][2][3]

Chaldene is about 3.8 kilometres in diameter, and orbits Jupiter at an average distance of 22,713,000 km in 699.327 days, at an inclination of 167° to the ecliptic (169° to Jupiter's equator), with an orbital eccentricity of 0.2916.

It was named in October 2002 after Chaldene, the mother of Solymos by Zeus in Greek mythology.[4]

It belongs to the Carme group, made up of non-spherical retrograde moons orbiting Jupiter at a distance ranging between 23,000,000 and 24,000,000 km and at an inclination of about 165°.
