How many times larger is the earth than an electron?

Answer 1

Using the classical value for the volume of an electron, which is equal to about 9.4×10−44 m3, and the volume of the Earth, which is equal to about 108.321x1019 m3, one can calculate how big the Earth is compared to an electron:

Volume of the Earth / Volume of an electron

108.321x1019 / 9.4×10−44

= 11.5x1063

Thus, the Earth is 11.5x1063 times larger than an electron

In other words, the Earth is 11500000000000000000000000000000000000000000000000000000000000000

or

11.5 thousand trillion trillion trillion trillion trillion times larger than an electron.

Edit: But, nowadays scientists can't say what size an electron is. So that gets us back to "don't know" and that's definite.
