Harpalyke (moon)

From Simple English Wikipedia, the free encyclopedia

Harpalyke or Jupiter XXII, 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 in 2000, and given the designation S/2000 J 5.[1][2] In August 2003,the moon was named after Harpalyke,[3] the incestuous daughter of Klymenos, who was in some accounts a lover of Zeus (Jupiter).

Harpalyke belongs to the Ananke group, believed to be the remnants of a break-up of a captured asteroid.[4][5] It is about 4 kilometres in diameter[6] and appears grey similar to C-type asteroids.[7] The moon orbits Jupiter at an average distance of 21,064,000 km in 624.542 days, at an inclination of 147° to the ecliptic (147° to Jupiter's equator) with an orbital eccentricity of 0.2441.
