# How much does the earth weigh?

It is a straightforward question and the answer is: it weighs 5.9736×1024 kilograms. Weight however alone does not give you enough of our planet’s vital statistics, so here some more.

The planet Earth has a mean radius of 6,371 km, an equatorial radius of 6,378.1 km, and a polar radius of 6,356.8 km. Those measurements help make why the planet is referred to as an oblate spheroid instead of a perfect sphere.

It has a total surface area of 510,072,000 square kilometers. Water covers 361,132,000 square kilometers while land covers the remaining 148,940,000 square kilometers. That is why water covers 71 percent and land covers 29 percent of the planet.
