What name is given to the largest moons of Jupiter?

The largest moons of Jupiter are known as the Galilean moons, named after the astronomer Galileo Galilei who first observed them in 1610. These four largest moons—Io, Europa, Ganymede, and Callisto—are particularly significant in the study of planetary science because they exhibit a variety of geological features and potential for harboring life. For instance, Europa has a subsurface ocean that might support life, while Ganymede is the largest moon in the Solar System and has its own magnetic field. Recognizing these moons as the Galilean moons emphasizes their discovery and classification, which play a crucial role in understanding the dynamics of the Jovian system and the nature of satellite formation around large gas giants. Other options do not specifically refer to this notable group of moons, making "Galilean moons" the correct and most appropriate designation.
