How Many Stars in the Sky?
... 8. The truthful answer to how many stars are in the sky is that no one really knows, because there are just too many to count. Stars are not evenly spread out in our universe but instead group together in galaxies. Our Milky Way galaxy alone is made up of an estimated 100 thousand million (100,000,0 ...
