* Earth's Density: The Earth's average density is about 5.52 grams per cubic centimeter (g/cm³).
* Moon's Density: The Moon's average density is about 3.34 g/cm³.
Why the difference?
* Composition: The Earth has a denser core made up mostly of iron and nickel. The Moon, on the other hand, has a smaller, less dense core and a composition that is more similar to the Earth's crust.
* Gravitational Compression: The Earth's larger mass exerts greater gravitational force, compressing its interior and increasing its density. The Moon, with less mass, has less gravitational compression.
In summary: The Earth's greater density is due to its heavier core and the gravitational compression that acts on it.
