Themisto

Themisto, also known as Jupiter XVIII, is a small and innermost prograde irregular satellite of Jupiter. It was discovered in 1975 and given its provisional designation S/1975 J 1. However, it was then subsequently lost because the moon has not observed long enough, and it was rediscovered by Scott S. Sheppard et al. in 2000 and given the provisional designation of S/2000 J 1.
Themisto orbits alone just like Valetudo and Carpo (before S/2018 J 4 was announced).
Themisto is about ~8 kilometers in diameter.
