How many Earth weighs: as scientists learned the mass of our planet

With help the advanced technologies people measure Earth in the most different ways. "High tech" tells how scientists measure the mass of a planet. The mass of Earth is estimated approximately in 5,972×10^24 kilogram. It is defined with help by combinations of the advanced methods. For example, scientists use gravitation measurements — measurement of gravitational forces. Highly sensitive gravity meters fix the smallest changes of gravitational acceleration in different places on the surfaces of Earth caused by changes in distribution of weight. Satellite measurements, such as experiment on gravitation and climate restoration (to English Gravity...
