Hermippe is a small moon orbiting Jupiter, one of many natural satellites that surround the giant planet. While it is relatively obscure compared to Jupiter's larger, more well-known moons, studying it contributes to our understanding of Jupiter's complex moon system and the broader dynamics of our solar system.

Hermippe /hɜːrˈmɪpiː/, also known as Jupiter XXX, is a natural satellite of Jupiter. It was discovered concurrently with Eurydome by a team of astronomers from the Institute for Astronomy of the University of Hawaiʻi led by David Jewitt and Scott S. Sheppard and Jan Kleyna 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 21.5 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.
