How is mass of earth calculated?
Are there any challenges in accurately measuring the mass of Earth?
Yes, there are several challenges in accurately measuring the mass of Earth, including the fact that it is difficult to measure the gravitational force between the Earth and a spacecraft or the Moon with extreme precision, and that the mass of the Earth is constantly changing due to factors such as the movement of tectonic plates and the addition of material from meteorites.
