Valetudo (//), also known as Jupiter LXII or S/2016 J 2, is a moon of Jupiter. 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, which also reported the discovery of nine other Jupiter moons.
Valetudo 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. It has a prograde orbit, but it crosses paths with several other moons that have retrograde orbits and may in the future collide with them.
The moon was provisionally designated as S/2016 J 2 until it received its name in 2018. The name Valetudo was proposed for it as part of its announcement, after the Roman goddess of health and hygiene, Valetudo, a great-granddaughter of the god Jupiter and approved by the IAU Working Group for Planetary System Nomenclature on 3 October 2018.
