Q:

Are some of Jupiter's moons bigger than Pluto?

A:

Orbiting Jupiter, Ganymede is the largest moon in our solar system. Saturn has some big moons as well, namely Titan. Both, Ganymede and Titan are bigger than Mercury and Pluto. Earth's Moon, Jupiter's moons Callisto, Io, and Europa, and Neptune's moon Triton are all larger than Pluto, but smaller than Mercury.
