Valetudo
Characteristics
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.[3] It has a prograde orbit which takes almost a year and a half to complete, but it crosses paths with several other moons that have retrograde orbits and may in the future collide with them.[6]
