Hermippe (moon)

From Wikipedia, the free encyclopedia

Hermippe (hər-mip'-ee, IPA: /hɚˈmɪpi/; Greek Ερμίππη), or Jupiter XXX, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2001, and given the temporary designation S/2001 J 3.^[1]^[2]

Hermippe is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 21,182 Mm in 629.809 days, at an inclination of 151° to the ecliptic (149° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2290.

It was named in August 2003 by the IAU, after Hermippe, a lover of Zeus (Jupiter).^[3]

Hermippe belongs to the Ananke group, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 Gm, at inclinations of roughly 150°.
