Kore is about 2 kilometers in diameter, and orbits Jupiter at an average distance of 23,239,000 km in 723.720 days, at an inclination of 141° to the ecliptic (139° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2462.

It belongs to the Pasiphae group, which is made up of 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°.

It was named after Kore, another name for the Greek goddess Persephone (from the Greek κόρη, "daughter [of Demeter]").^[5]
