Jupiter's Moons

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 magnetic field. Callisto is heavily cratered and has a thin atmosphere. Io is the most volcanic body in the solar system, with intense volcanic activity. Europa, with its subsurface ocean, is a prime candidate for extraterrestrial life. The video also discusses smaller moons and their characteristics, emphasizing the diversity and complexity of Jupiter's satellite system.
