Do we know how much Planet Earth weighs? Yes. Thanks to Isaac Newton's Law of Universal Gravitation. It can be used to calculate the mass of the Earth in terms of the gravitational force on an object (its weight) at the Earth's surface.

And we use the Radius of Earth as the distance.

The Earth Weighs about 13 Septillion, 170 Sextillion pounds. 13,170,000,000,000,000,000,000,000 pounds or 5,974,000,000,000,000,000,000,000 kilograms.
