Eirene

Eirene, also Jupiter LVII and provisionally known as S/2003 J 5, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003.
Eirene is about ~4 kilometres in diameter, and orbits Jupiter at an average distance of 23,974,000 km in 743.88 days, at an inclination of 166° to the ecliptic, in a retrograde direction and with an eccentricity of 0.307.
Eirene was considered lost after its discovery and was later recovered in 2017 and also received its permanent designation.
Eirene belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter in the opposite direction.
