## What is the Mass of the Earth?

Earth is a planet we all are curious to know about, Our Planet Earth is known to have an approximate mass of 6*1024 kg, or you can also consider it as 6000 trillion tons. The amount is used to calculate the mass of another planet in space science ( astronomy and astrophysics) as a unit of mass to take out the relative mass of other planets.

## Mass of other Planets of Solar System

The table lists the mass of each planet in the solar system. Check the comparison of the weight of planets concerning the earth. 3 planets have less weight than the planet earth and four have more weight than the Earth.

 Planet Mass Relative to the Mass of Earth Mercury 3.3*1023 0.0553 Mars 6.4*1023 0.107 Venus 4.87*1024 0.815 Earth 6*1024 1 Uranus 8.68*1025 14.5 Neptune 1.02*1026 17.1 Saturn 5.68*1026 95.2 Jupiter 1.9*1027 318

Summary:

## How To Calculate The Mass Of The Earth?

The mass of Earth is measured by determining other quantities that included, including Earth’s density, gravitational constant, and gravity. Schiehallion experiment is the first measurement done in the year 1770 that resulted in a value about 20% too low. In 1778, the Cavendish experiment discovered the correct value within 1%.

To calculate the Mass Of The Earth, here’s an example, consider the radius of the earth to be R and the mass of the earth to be M, and a body of mass ‘m’ on the surface of the earth. Now, the distance of the body from the earth’s center will be equal to the radius R of the earth.

Now, Considering the law of gravitation, the gravitational force F of the earth acting on a body is given as 6 × 1024 kg.
