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

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
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
Solid is like a toy, a gas is like air in a balloon, I dont know what liquid looks like
