Eurydome is about 3 kilometres in diameter, and orbits Jupiter at an average distance of 23,231,000 km in 723.359 days, at an inclination of 149° to the ecliptic (147° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.3770.

It was named in August 2003 after Eurydome in Greek mythology, who is sometimes described as the mother of the Graces by Zeus (Jupiter).[4]

Eurydome belongs to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 Gm, and with inclinations ranging between 144.5° and 158.3°.
