Valetudo (/vælɪˈtjuːdoʊ/), also known as Jupiter LXII, is a moon of Jupiter.^[3]^[4] 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.^[2] 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.^[5] It 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^[5] and approved by the IAU Working Group for Planetary System Nomenclature on 3 October 2018.^[6]
