Lysithea

Lysithea was a moon of Jupiter. It was discovered in 1938 by Seth Barnes Nicholson, who also found Carme the same year. By the early 24th century, it was considered one of the Ancient Twelve. Whilst the other moons around the planet were destroyed as part of a spring cleaning of the Sol system, Lysithea was preserved due to its status. (PROSE: To the Slaughter)
