S/2011 J1

S/2011 J1 is one of Jupiter's irregular moons. It was discovered in 2011, by a team of astronomers led by Scott S. Sheppard. S/2011 J1 is part of the Carme Group, a collection of irregular moons with similar orbital characteristics. S/2011 J1's small size and distant orbit around Jupiter limit the available 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/2011 J1 are believed to have originated from captured asteroids or fragments resulting from collisions.
