The Earth has a mass of approximately 5.97 x 10^24 kilograms (5.97 trillion trillion kilograms or 5.97 sextillion kilograms). However, weight is a measure of the force exerted on an object due to gravity and depends on the mass of the object and the strength of the gravitational field it is in. On the surface of the Earth, the gravitational force is approximately 9.81 meters per second squared (m/s^2), which means that the weight of the Earth is approximately 5.97 x 10^24 kilograms multiplied by 9.81 m/s^2, or approximately 5.87 x 10^25 Newtons.
