Best Answer: Mass of earth = 5.9742 Ã 10^24 kilograms. To Calculate, Force of gravity F = G.m1.m2 / r^2. where m1 and m2 are two masses, and G is gravitational constant and r is distance. let m1 = M (mass of the Earth) So, F = G.M.m2 / rÂ². Now, assume m2 is a mass on the surface of the planet.
Earth's two cores. There are two cores inside the Earth. The average density of the Earth is 5,515 kilograms per cubic meter. The Earth's crust density is 3,000 kilograms per cubic meter. Therefore scientists decided the core must contain iron and other heavy metals that sank to the center as the Earth was forming.
