Eirene /aɪˈriːniː/, also Jupiter LVII and originally 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 Hawaiʻi led by Scott S. Sheppard in 2003 but was then lost. It was recovered in 2017 and given its permanent designation that year.
