Ganymede, one of Jupiter's moons, has a diameter of about 5,268 kilometers, making it the largest moon in the solar system. In terms of volume, Ganymede can contain approximately 2.5 times the volume of Earth. Therefore, about 2.5 Earths could fit inside Ganymede, although this is a rough estimate since it depends on the specific measurements and shapes considered.
