Valetudo (a.k.a. Jupiter LXII, originally known as S/2016 J 2) is a moon of Jupiter.[5][6] It was discovered by Scott S. Sheppard and his team in data reaching back to 2016, but was not announced until July 17, 2018, via a Minor Planet Electronic Circular from the Minor Planet Center.[3] It has a diameter of about 1 km (0.6 mi) and orbits Jupiter at a distance of about 19 million kilometres (12 million miles). Its orbital inclination is 34 degrees, and its orbital eccentricity is 0.222.[1] It has a prograde orbit, but it crosses paths with several moons that have retrograde orbits and may in the future collide with them.[7] The name Valetudo /vælɪˈtd/ was proposed for it as part of its announcement, after the Roman goddess of health and hygiene, Valētūdo, a great-granddaughter of the god Jupiter[7] and approved by the IAU Working Group for Planetary System Nomenclature on 3 October 2018.[8]
