Relative to erf sure but what of the rest of the universe ?
Hmmm.... let's see...

The number of stars in the galaxy is on the order of 10 ^11, and the number of galaxies is also on the order of 10^11, so that' 10 ^22 stars. If only 1% of them have planets, that's 10^20 planets.

To put that in perspective, the number of dollars in the national debt is on the order of 10^ 10, so the number of pennies is 10^12.

So, there are 100,000,000 planets for every penny of the national debt.

Out of all those planets, no doubt some have more than 79 moons.
