Weight of the earth?

Question

does anyone knows how much the earth weighs?

Answer 1

It is estimated to be 4.6 sextillion tons. However, since we have not been deeper than about 7 miles into the crust, we have no idea of the actual density of the other layers.

Answer 2

Physical Characteristics:

Surface area - 510,072,000 km²

148,940,000 km² land  (29.2 %)

361,132,000 km² water (70.8 %)

Volume - 1.0832073×10^12 km³

Mass - 5.9736×10^24 kg

Answer 3

The earth doesn't have weight, since weight is defined by the gravitational force acting between the earth and another object.   Also, since the earth is floating in space in orbit around the sun, it is literally weightless relative to the sun's gravitational field.  Meaning there is no force between the earth and the sun that you can measure.   However, the earth has mass, which is about 5.97 x 10^24 kg.

You could say this is equivalent to 6.58 x 10^21 or 6,580,000,000, 000,000,000,000 tons of rock, or 5.85 x 10^19 Meganewtons, if you could weigh it.  But that is not very meaningful, except to give you a vague feeling of its immensity.
