S/2003 J18

S/2003 J18 is one of Jupiter's irregular moons, discovered in 2003, by a team of astronomers led by Brett J. Gladman. S/2003 J18 is part of the Ananke Group, which is a collection of irregular moons with similar orbital characteristics. S/2003 J18’s small size and distant orbit around Jupiter make it challenging to obtain detailed information about its physical characteristics, composition, and surface features. It follows a retrograde, highly inclined orbit around Jupiter, moving in the opposite direction of the planet's rotation and at an angle to the plane of Jupiter's equator. Irregular moons like S/2003 J18 are believed to have originated from captured asteroids or fragments resulting from collisions.
