The Number of Stars in the Known Universe

There are 10 times more stars in the sky then there are grains of sand found on all the beaches and deserts of earth and that is based just on those that can be seen by our current telescopes today. In truth, there are many more out there than this.

That is: 7.0 x 10^22 Stars or 70,000,000,000,000,000,000,000 Stars.
