Does the earth weigh anything in space?

Answer 1

Yes.
Weight is a force (mass x acceleration)
F = m . a
Earth has mass. And it is accelerating towards Sun, for instance. That´s why the sun can keep it in orbit.
So, if you multiply the mass of the Earth times the gravitational pull of Sol, you have the total weight; same as you weight something because of g (earth acceleration) on earth.

Earth mass= 5.9742×10^24 KG; Sol's acceleration due to gravity = 274.13 m/s²

5.9742×10^24 KG x 274.13 m/s² = Earth Weight

It's useless to "weigh" a planet, but that's it. Always need something to pull.

Answer 2

When we say "weight" we mean, how strongly is something attracted to the earth by gravity. So, you wouldn't say that the earth has "weight." But obviously the earth does consist of a really big object that is made of stone and metal and water. So how do you describe that stuff? We call it "mass." The earth has mass and you have mass. Your mass might be say, 50 kilograms, or about 110 pounds. If you are on the Earth the earth's gravity will attract you and you can measure the attraction as weight. But if you were out in space far from the earth, what would you weigh? Nothing because you would not be attracted by the earth - too far away. You still have the same amount of stuff in your body though, so your weight is zero, but your mass is the same as when you were on the earth - that is, you have the same amount of body.... get it?

So, what about if you were on the moon, or Mars. Those planets do not have as strong a gravity attraction - you would still have the same size body - the same mass, but it would not be attracted as strongly as on earth, so you would "weigh" less.

Answer 3

Yes. There is a gravitational force between the earth and the sun, and where there's gravity, there's weight. Every object with mass weighs "something" because there's always some other object in the galaxy on which to exert gravity. It some cases it might be ridiculously weak, but it's there. There's even a gravitational pull between my computer monitor and me, but the reason it doesn't fly into my face is because the biggest object next to me is the earth, so that's what me and my monitor are pulled towards.

Answer 4

No. Weight is the measurement of the pull of gravity on an object dependant on its mass. So since there isn't any gravity pulling down on the earth, it doesn't weigh anything. However, it does have a mass, which in basic terms is the amount of stuff in an object.

Answer 5

Not really. Maybe a few newtons (or pounds, if you prefer that unit).

If it did weigh anything, it would fall in the direction of the weight (nothing to stop it). Since the Earth isn't falling anywhere that we can tell, I would say that it's doesn't have any weight.

You do mean Earth, the planet, don't you? I'm not talking about taking a hand full of dirt to outer space.

Any astrodynamics types out there with a better answer?

Answer 6

Not alone in space, but it will have weight near a larger body like the sun or jupiter because they pull on the earths mass. Weight is the pull something has on its mass.

Answer 7

yes. It depends on what you are weighing it to though. For instance it might weigh a tiny bit with mars, but it wieghs a lot compared to sun. This is because wieght is really just the magnitude of gravity.

Answer 8

no. weight is the amount of pressure the gravtiy applies on you. usually the amount applied to a scale when it is between you and the earth. since space has no gravity, there is no weight. the earth has mass so it is there and is put in an orbit around the sun using the suns gravtiy and inertia. but to truely answer your question, no.

Answer 9

no, but it still has mass. weight is caused from gravity on an object. Since gravity comes from the earth itself, the earth does not weigh anything

Answer 10

I read someplace on an article on astronomy,if the earth would be weighted on a giant scale,the weight would be 6.6 sextillion tons
