The Earth Weighs About 13,170,000,000,000,000,000,000,000 Pounds

Earth may be too big to pop on a scale, but, according to NASA and the California Institute of Technology’s Cool Cosmos, scientists have used their knowledge of the laws of gravity and applied that to some fancy-schmancy mathematical equations to figure out that our planet weighs about 13,170,000,000,000,000,000,000,000 pounds.
