The Jovian system refers to the collection of celestial bodies that orbit the planet Jupiter, the largest planet in our solar system. This system includes four major moons known as the Galilean moons: Io, Europa, Ganymede, and Callisto. These moons are significant for their unique geological features and potential for hosting life, particularly Europa, which is believed to have a subsurface ocean. In addition to the Galilean moons, the Jovian system contains numerous smaller moons and a faint ring system. Jupiter's strong gravitational pull influences these moons and the surrounding space, making it a dynamic environment. The study of the Jovian system helps scientists understand planetary formation and the potential for life beyond Earth.
