    Jupiter LXI, provisionally known as S/2003 J 19, is a natural satellite of Jupiter. It was discovered by a team of astronomers led by Brett J. Gladman, et al. in 2003.[2][3]

    S/2003 J 19 is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 22,709 Mm in 699.125 days, at an inclination of 165° to the ecliptic (164° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.1961.

    It belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm and at an inclination of about 165°.

    This moon was lost following its discovery in 2003.[4][5][6] It was recovered in 2018[7] and given its permanent designation that year.[8]
