Jupiter's Moons and Their Features

The video explores Jupiter's moons, focusing on the four largest: Ganymede, Callisto, Io, and Europa. Ganymede is the largest moon with a possible iron core and ocean. Callisto is heavily cratered with a thin atmosphere. Io is the most volcanic body in the solar system, while Europa has a subsurface ocean that may harbor life. The video also discusses smaller moons and their characteristics.
