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 :)
