Eirene is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 23,974,000 km in 758.341 days, at an inclination of 166° to the ecliptic (167° to Jupiter's equator), with an orbital eccentricity of 0.307.

It belongs to the Carme group, made up of non-spherical retrograde moons orbiting Jupiter at a distance ranging between 23,000,000 and 24,000,000 km and at an inclination of about 165°.
