Compared with the other moons of Jupiter, the four Galilean moons areGroup of answer choicesLargerYoungerFarther from JupiterLighter

The four Galilean moons of Jupiter—Io, Europa, Ganymede, and Callisto—are notable for several characteristics. When comparing them to the other moons of Jupiter, the correct choice among the options given is that they are larger. Ganymede, the largest of the Galilean moons, is even larger than the planet Mercury.

1. Larger: The Galilean moons are indeed larger than most of Jupiter's other moons. While Jupiter has many small moons, the Galilean ones stand out due to their significant size.

2. Younger: This option is misleading; the age of the moons is not necessarily younger compared to other moons of Jupiter.

3. Farther from Jupiter: The Galilean moons are not farther from Jupiter when compared to other moons; in fact, they are among the largest and closest to the planet.

4. Lighter: Their mass is not significantly less compared to other larger moons.

In summary, the Galilean moons are primarily distinguished by their larger sizes compared to other moons of Jupiter.
