Hegemone (moon)

Hegemone or Jupiter XXXIX, is a moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003, and given the designation S/2003 J 8.^[1]^[2]

Hegemone is about 3 kilometres in diameter, and orbits Jupiter at an average distance of 23,703,000 km in 745.500 days, at an inclination of 153° to the ecliptic (151° to Jupiter's equator), with an orbital eccentricity of 0.4077.

It was named in March 2005 after Hegemone, one of the Graces, and a daughter of Zeus (Jupiter).^[3]

Hegemone belongs to the Pasiphaë group, non-spherical retrograde moons orbiting Jupiter at distances ranging between 22,800,000 and 24,100,000 km, and with inclinations ranging between 144.5° and 158.3°.
