How weighty is the Earth?

Answer 1

The MASS of Earth is about 6x10^24 kilograms (that a 6 with 24 zeros after it). In science, mass and weight are two different things. As a result, asking for the weight of the Earth doesn't really make sense.

For example, I could say that I weigh 120 pounds on Earth, but if I went to the Moon I would only weigh 20 pounds. But no matter where I am my mass will always be 55 kilograms. Weight depends on the local strength of gravity. Here on Earth, the strength of gravity depends on the Earth itself! So it doesn't make any sense to talk about Earth's weight. Mass, on the other hand, is simply a measure of the amount of matter an object has, which will never change no matter where that object is in space.

Answer 2

That would depend on the gravitational force exerted on it.
Earth's gravity being 1
Theoretically, if you were to take the Earth out of space where it has no weight (only mass), compress it down to the size of a bowling ball, and then put it on a scale on the surface of a planet that had the same gravity as Earth, just before it completely destroyed the scale and started to smash through the ground toward the centre of the planet, it would register something like a thousand trillion metric tons on the scale.

Answer 3

I agree with Kris, with one addition: weight is mass under the influence of a force of gravity. On earth it is easy to determine our weight by multiplying our mass with the Earth's gravity, approximately 9.81 m/s^2. The resulting term is then called our weight in Newtons. I don't know what the gravitational acceleration of the sun is upon the Earth, by the formula depends on the masses of the two bodies times a constant and is divided by the swuare of the distance between the two bodies. Once gravity has been determined then Newton's Second Law, F=Ma, determines the weight of the Earth, in relation to the sun. I could do the math but I will let you do it instead.

Answer 4

I'm not sure what you asking, if your asking how much dose the weigh, Well theoretically nothing We Are in a stable orbit around the sun, which helps hold us where we are, and the fact that there is no friction in space nor gravity. But there is just no way of really knowing we don't even know what the core of the earth really is there are theory's but no facts, and with out that you have a open ended problem. Sorry i wish i could tell you more.

Answer 5

Volume >>> 1.083 207 3×1012 km³
Mass >>> 5.9742×1024 kg
Density >>> 5,515.3 kg/m³
