This can be derived from gravity calculations, in combination with the size of the moon (diameter, circumference, etc.)

Ganymede is solid, as are all the moons in the solar system. However, the fact that Ganymede is a moon means that it is not a planet.
a feather is a solid

Mica is a solid

It's a solid
The moon has a solid (terrestrial) surface.
No, the moon is not a big ball of gas. It is a solid celestial body that orbits around the Earth.
i dont know either maybe a gas? i dont know either maybe a gas? for those who dont know: beryllium is a solid!
Ganymede is solid, as are all the moons in the solar system. However, the fact that Ganymede is a moon means that it is not a planet.
The moon is not a star it is a moon. A star is made of gas - the moon is solid But it is the only object to orbit the earth
The Earth and the Moon are not made mostly of gas but the Sun is.
i know
Callisto is a solid moon, primarily composed of ice and rock. It has a surface covered with a mix of ice and rocky material, with many impact craters indicating its geological history. Unlike gas giants, Callisto lacks a significant atmosphere, reinforcing its classification as a solid body.
It is a gas, Saturn is known as a gas Giant. However its rings are solid chucks of ice and rock.
matter is solid water or gas
