Jupiter hosts more than 100 moons, with most attention focused on the four Galilean moons: Io, Europa, Ganymede and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body in the solar system and Europa having a vast subsurface liquid-water ocean beneath its icy crust. However, Jupiter's smaller, lesser-known moons could provide astronomers with key insights into the history of the solar system because they have remained largely unchanged, unlike the Galilean moons.
