The mass of the Earth is approximately 6,580,798,520,700,000,000,000 tons.
Earth is also the densest planet in our solar system at 5.5 grams per cubic centimeter. Mercury is the second most dense of our neighbors, and would be much more so if it weren’t so small. Earth has a major advantage because its size causes so much gravity that it compacts itself down much tighter than smaller planets.
