Valetudo //, also known as Jupiter LXII and originally known as 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 17 July 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 ('Health') was proposed for it as part of its announcement, after the Roman goddess of health and hygiene (a Latin translation of Greek Hygieia 'Health') and a great-granddaughter of the god Jupiter. The name was approved by the IAU Working Group for Planetary System Nomenclature on 3 October 2018.
