The earth has no weight because it's not an object sitting on the earth.
Weight is merely the force of earth's gravity acting on an object.

Earth weighs about 13,170,000,000,000,000,000,000,000 pounds (or 5,974,000,000,000,000,000,000,000 kilograms). Since Earth is too big to be placed on a scale, scientists use mathematics and the laws of gravity to figure out Earth's weight.
It would be more proper to ask, "What is the mass of planet Earth?"1 The quick answer to that is: approximately 6,000,000,000,000,000,000,000,000 (6E+24) kilograms.
The radius of the Earth is 6,400,000 meters (6,999,125 yards). If you plug all of these values in and solve for M1, you find that the mass of the Earth is 6,000,000,000,000,000,000,000,000 kilograms (6E+24 kilograms / 1.3E+25 pounds).
1 It is "more proper" to ask about mass rather than weight because weight is a force that requires a gravitational field to determine. You can take a bowling ball and weigh it on the Earth and on the moon. The weight on the moon will be one-sixth that on the Earth, but the amount of mass is the same in both places. To weigh the Earth, we would need to know in which object's gravitational field we want to calculate the weight. The mass of the Earth, on the other hand, is a constant.

Mass of the earth is 6*10^24 kg. We never talk of weight of earth. We can work out the force of attraction between Sun and Earth which is53.39*10^31 Newtons.

Scientists are now saying the Earth is a little lighter than we thought. The calculated weight is 5.978 sextillion metric tons, or 5,978 followed by 18 zeros. But the latest measurements show the true weight is actually 5.972 sextillion metric tons.

The Earth's mass is about 5.98 x 10 to the power of 24 kg.

well, as no one knows for sure what is at the centre of the earth (although we can guess pretty accurately) it's impossible to say.
a damned lot! xx

Thats a very interesting question. I think you should email NASA and see what response you get

About 5.94x10^24kg I think.
