If a solid were placed on the moon, would its density change?

O No, density is a measure of a mass to volume ratio. Mass does not change between planetary
objects.

O Yes, density is a measure of a mass to volume ratio. Mass does change between planetary objects.

O No, density is a measure of weight to volume ratio. Mass does not change between planetary
objects.

O Yes density is a measure of a weight to volume ratio, Weight does not change between planetary
objects.

Moving from the gravity of the Earth to the gravity of the moon, the astronaut’s weight certainly changes, but his mass remains the same. There is less air pressure in space, but astronauts don’t blow up like bubbles once they leave Earth’s atmosphere, so you can safely assume that the astronaut’s volume doesn’t really change either. If the mass and the volume don’t change on the moon, you can deduce that the astronaut’s density would be the same.
