Hermippe (/hərˈmɪpiː/ hər-MIP-ee; Greek Ερμίππη), or Jupiter XXX, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the Institute for Astronomy of the University of Hawaii led by David Jewitt and Scott S. Sheppard in 2001, and given the temporary designation S/2001 J 3.
Hermippe is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 21 million kilometers in about 630 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).
Hermippe belongs to the Ananke group, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 gigametres (0.152 astronomical units), at inclinations of roughly 150°.
