The radius of the Earth is 6,400,000 meters (6,999,125 yards). If you plug all of these values in and solve for M1, you find that the mass of the Earth is 6,000,000,000, 000,000,000,000,000 kilograms (6 x 1024 kilograms, or 1.3 x 1025 pounds). read more
If you plug all of these values in and solve for M1, you find that the mass of the Earth is 6,000,000,000, 000,000,000,000,000 kilograms (6 x 10 24 kilograms, or 1.3 x 10 25 pounds). 1 It is "more proper" to ask about mass rather than weight because weight is a force that requires a gravitational field to determine. read more
Earth is also the densest planet in the Solar System, with a mean density of 5.514 g/cm 3 (0.1992 lbs/cu in). Between its size, composition and the distribution of its matter, the Earth has a mass of 5.9736×10 24 kg (5.9 trillion trillion kilograms) or 1.31668×10 25 lbs (13 billion trillion tons). read more
That’s 5,972,000,000,000,000,000,000 tons and gaining! Scientists refer to this measurement as the Earth’s mass instead of weight since weight is the result of Earth’s gravitational pull on another object, and the Earth cannot pull on itself! As the Earth orbits the Sun, it is weightless. read more
