    How much does the Earth weigh?

    Has the Earth ever been weighed?

    From what i know weight is based on gravitational pull.  This is why we weigh less on the moon compared here on earth.  So the weight of the earth is dependent on another mass.  on the other hand, the mass of an objet remains constant regardless of the gravitational pull.  Anyway, some websites put the number at 6.6 sextillion tons, that's with 20 zeros after 6.6.  Other sites put it at 5.98 followed by 22 zeros kilograms.

    Hi Myn Is Me,

    Because our earth is suspended in space, it cannot be put on a scale and weighed. However, scientists have estimated Earth's weight by identifing the weight of each of its parts, such as the crust, the mantle and core.

    All put together would add up to 6.6 sextillion tons. To visualize how this number looks like on paper it would resemble something like this: 6,600,000,000,000,000,000,000

    Scientists have also estimated that the earth’s mass increases by 100,000 lbs each year, which is approximately 453.59237 kilograms (were we to calculate in other weight units) from dust particles and other meteoric material crashing down from space to Earth.
    Interesting question smile

    Yes, by several scientists. Its weight was first found by experiment in 1797-98 by an Englishman, Henry Cavendish, who estimated that our globe weighs about five and a half times as much as an equal bulk of water, its weight being 12,500,000,000,000,000,000,000,000 pounds. His estimate agrees very closely with the calculations of later experimenters.

    Very excellent question, Myn Is Me.  Technically, the mass of the earth is measured in slugs in our archaic english system of units. We are so used to using units of force to describe mass in this country that even I do this when the conversation is casual.  The earth weighs nothing if it is all alone in outer space. The earth has a mass of  5.98 X 10^24 kilograms.  As I said, loosely speaking we can compare this to 6.59 X 10^21 tons, which, remember is a unit of force, and that depends on the masses of the bodies and the distance between their centers of mass.

    The weight of the earth in relation to only  the sun  is 3.53 X 10^22Newtons( 3.965 X 10^18 tons). Technically, the earth still weighs nothing in realation to the sun because centrifugal force balance this out, as for example when astronauts are "weightless" in orbit.
