WebJul 23, 2024 · The mass of an object is measured by its resistance to a force. When you pick something up to test its weight, it is resisting the Earth’s gravity, so an everyday object’s weight on Earth is indeed one measurement of its mass. But there’s more to mass than just a resistance to gravity, especially on the scale of the smallest pieces of matter. WebThere, only mass can cause a gravitational force.

WebFrom the gravity standpoint, sure. Surface gravity is proportional to M/r^2, so you want planet mass M to be double as well. Area is proportional to r 2, so 2 x the surface area means sqrt(2) x the radius, which means 2^(3/2) or 2.82 times the volume.. That means the average density = M/V is 2/2^(3/2) = 1/sqrt(2) = 0.707 times that of Earth.
