Eirene

Eirene is one of Jupiter's irregular moons. It was discovered in 2003, by a team of astronomers led by Scott S. Sheppard. Eirene is part of the Carme Group, a collection of irregular moons with similar orbital characteristics. Due to its small size and distant orbit around Jupiter, limited information is available about Eirene's 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 Eirene are believed to have originated from captured asteroids or fragments resulting from collisions.
