Erinome

Erinome (pronounced /ɛˈrɪnɵmi/ err-RIN-o-mee, or as in Greek Ερινόμη), also known as Jupiter XXV, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard et al. in 2000, and given the temporary designation S/2000 J 4.[1][2]

Erinome is about 3.2 kilometres in diameter, and orbits Jupiter at an average distance of 22,986 Mm in 711.965 days, at an inclination of 164° to the ecliptic (162° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2552.

It was named in October 2002 after the mythological Erinome, said to be a "daughter of Celes, compelled by Venus to fall in love with Jupiter."[3]

Erinome 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°.
