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
inclination of 150° to the
ecliptic
The ecliptic or ecliptic plane is the orbital plane of Earth's orbit, Earth around the Sun. It was a central concept in a number of ancient sciences, providing the framework for key measurements in astronomy, astrology and calendar-making.

IAUC 8023: Satellites of Jupiter
2002 November 29 (correcting the name) Despite this correction, some earlier research still referred to the moon as Magaclite.
It belongs to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.7 Gm, and with inclinations ranging between 144.5° and 158.3°. However, while Pasiphae belongs to the grey color class (V=17.22 B−V=0.74, V−R=0.38), Megaclite falls under the light red color class (V=22.07 B−V=0.94, V−R=0.41), similarly to Callirrhoe and Sinope.
