Euporie is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 19,088 Mm in 538.780 days, at an inclination of 145° to the ecliptic (145° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.144.

It was named in August 2003 after Euporie, a Greek goddess of abundance and one of the Horae in Greek mythology (and thus a daughter of Zeus).[6] It is a member of the Ananke group.
