approximately how many stars are there in the sky

The stars visible to the naked eye ... those with "visual magnitudes" of roughly 6 or lower ... total about 5,000 or 6,000.When you introduce optical aid ... telescopes etc. ... the number immediately becomes uncountable.-- The part of our own galaxy ... the "Milky Way" ... that we can see and photograph, leads us to estimate that there are a total of 200 to 400 billion stars, in our own galaxy alone. -- The number of galaxies we see on various photographic images leads us to estimate the number of galaxies in the observable universe at something like 100 to 300 billion galaxies.  But a recent German supercomputer simulation put that number nearer to 500 billion galaxies.  In other words, there could be a galaxy out there for every
star in the Milky Way, and billions of stars in every one of them !Now you do the math.  And remember, we're only talking about the observable universe.  We don't see any end to it, and we don't have light-gathering monsters to see any farther than that, so there's even more to it.

We have over one billion galaxies in the universe.In our milky way, we have around 300 billion stars. Astronomers don't know for sure how many stars there are, considering the universe goes on and on and on (etc)But did you know, there are more stars than every grain of sand here on earth?!
