 Themis (hypothetical moon)

Themis is a hypothetical moon that has been proposed as a potential natural satellite of the dwarf planet Haumea, which is located in the Kuiper Belt beyond Neptune. The existence of Themis was suggested based on observations and models regarding Haumea's unique characteristics, including its rapid rotation and potential collisional history. The proposed moon is thought to be relatively small and could be a fragment resulting from past collisions involving Haumea.
