Question: 1 / 460

What is the name of Jupiter's largest moon?

Callisto

Europa

Ganymede

Jupiter's largest moon is known as Ganymede. It holds the distinction of being not only the largest moon of Jupiter but also the largest moon in the entire Solar System. Ganymede has a diameter of about 5,268 kilometers (3,273 miles), which is even larger than the planet Mercury. This moon is unique because it has a magnetic field, probably generated by a partially liquid iron or iron-sulfide core, which is rare among moons. Furthermore, Ganymede displays a varied surface composition, featuring both older, heavily cratered regions and younger, less cratered areas that show signs of geological activity. These characteristics make Ganymede an interesting object of study in planetary science and astrobiology.
