Megaclite is about 6 kilometres in diameter, and orbits Jupiter at an average distance of 24,687,000 kilometers in 747.09 days, at an

Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object.
