      The weight of the earth is 5.972 × 10^24 kg. It is interesting to know how it is calculated. The mass of the Earth may be determined using Newton’s law of gravitation. It is given as the force (F), which is equal to the Gravitational constant multiplied by the mass of the planet and the mass of the object, divided by the square of the radius of the planet.
