I heard billions, but I'm not really sure.

almost each and EVERY blob (galaxy) is basically about a billion to 5 billion stars each.....
and this is about 1cm of space
(seen from your eye's point of view)

Answer 2

There are billions visible, but scientists concentrated a telescope at a patch of dark sky where there were no visible stars or constellations. The area was no larger than what you would see if you looked up to the sky through a drinking "straw." After leaving the telescope in place for a period of time, it revealed many previously unknown constellations, I believe the number was forty-two. So the number of stars in the sky is unbelievably large. Don't forget that many of the "stars" we see in the sky are actually constellations, containing many, many stars

Answer 3

There are about 100 billion galaxies in the observable universe, and each has an average of 100 billion stars. That's a lot of stars (100 billion times 100 billion).

But on the clearest night on Earth, the total number of stars that could be seen with the naked eye over the entire Earth is only about 6000.
So at one location, over the course of one clear night, a person would only see half that (summer or winter constellations), and only half of that (northern hemisphere or southern hemisphere).
So a person could at most see 1500 stars on any one clear night.

Answer 4

How many stars in the universe? billions of billons. An interesting question would be "how many visible stars are there in the night sky." This would depend on the eyesight of the individual and the conditions. A person with 20/20 vision and with perfect star gazing conditions should traditionally be able to see magnitude 6.5 and brighter. There is certainly a finite number of 6.5 and brighter stars in the sky! That number is... 9,110!

Answer 5

Of stars that can be seen the sky with the naked eye, there are about 5000-6000. Stars in our Miky Way galaxy, about 10^11. Of total stars in the Universe, perhaps 10^20.

Answer 6

Space is infinite as far as we can tell, so the exact amount of stars is unknown. That's why you,ve heard billions, and there might even be more than that.

Answer 7

On heavily overcast nights, none.
