S/2017 J8

S/2017 J8 is one of Jupiter's irregular moons, discovered in 2017 by astronomer Scott S. Sheppard. S/2017 J8 is part of the Carme Group, which is a collection of irregular moons with similar orbital characteristics. S/2017 J8’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/2017 J8 are believed to have originated from captured asteroids or fragments resulting from collisions.
