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). [ [http://cfa-www.harvard.edu/iauc/08100/08177.html IAUC 8177: "Satellites of Jupiter, Saturn, Uranus"] 2003 August 8 (naming the moon)]
