Megaclite

Megaclite /mɛɡəˈklaɪtiː/, also known as Jupiter XIX, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000, and given the temporary designation S/2000 J 8.[5][1][6]

    Megaclite is about 6 kilometres in diameter, and orbits Jupiter at an average distance of 24,687,000 kilometers in 792.437 days, at an inclination of 150° to the ecliptic (148° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.308.

    It was named in October 2002 after Megaclite, mother by Zeus (Jupiter) of Thebe and Locrus in Greek mythology.[7][8]

    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°.
