According to Jefferson Lab, an average 70 Kg person, that's about 150 lbs, will have approximately 7*10 to the 27th atoms in their body. That's 7 followed by 27 zeros (7,000,000,000,000,000,000,000,000,000).

The number of stars in the Universe, which is estimated at 10*10 to the 21, or 10 followed by 21 zeros. (10,000,000,000,000,000,000,000).

So you can see that there are way more atoms in your body than there are stars in the universe.

No matter where the atoms are the size of the atom and the distance between them is so small that a number or comparison would nothing to you and I.
