2. How to Calculate the mass of Earth The mass of the earth can be known through observation satellites in a long time. The speed of a satellite circling the earth is affected by the mass of the earth. So if we know the distance, and the time it takes a satellite to orbit the earth, we can estimate the mass of the earth.

3. The Way to Calculate the Mass of Earth Volume of Earth = (4 / 3) .π .R .R .RR is radius earth = 6371 kmThen,Density = mass / volumeDensity of Earth is estimated to = 5:51 g / ccEarth mass = density of earth / earth volume

5. g : Acceleration of gravity at the surface of the Earth(m/s .s)

6. Rearth: Radius of the Earth(m)

8. Main Ingredients Of Earth Main content of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%) , calcium (1.5%), and aluminum (1.4%), and 1.2%, the rest consisting of various rare elements. Because the process of mass segregation, the core of the earth is believed to have the main content of iron (88.8%), and a little nickel (5.8%), sulfur (4.5%), and the rest less than 1% of rare elements.
