Answer 2

The earth weighs 13,170,000,000,000,000,000,000,000 pounds. You can say this number like this: 13 octillion, 170 septillion. That’s A LOT more than a million, billion, or trillion pounds!

To put things in perspective:

One male African bush elephant weighs 13,000 pounds.

100 elephants would weigh 1,300,000 (one million, 300 thousand) pounds.

One million elephants would weigh 13,000,000,000 (13 trillion) pounds.

One trillion elephants–there are not even this many on earth–would weigh 13,000,000,000,000,000 (13 quintillion) pounds.
