How many stars observable to the naked eye are in the universe?
In general terms, with people of normal vision, there are in total around 8,000 stars observable with the naked eye. This breaks down to 4,000 in the north, and 4,000 in the south, non-overlapping. But in the north, for example, half the stars in your year-round sky are obscured by the sun; so roughly 2,000 stars are visible, on average, in the nighttime sky on any night. And this assumes very good viewing conditions. This may not sound like a very high number, but we have become used to hearing astronomical things described with correspondingly huge numbers. Try coming up with a method of estimating the number of stars you actually see; you probably won't be too far off from 2,000 if you do it carefully. We are talking about stars in the Milky Way; a small number of galaxies and clusters can be seen as 'stars' with the naked eye, but no stars outside of the Milky Way are observable..

It isn't possible to put an exact number to it, because it all depends on the amount of light pollution, other pollutants and the state of your eyes. An average person wil…l be a able to see about 2,000 stars, the top limit around 5,000. (MORE)
About 6000, under very good viewing conditions. Of these, about half (3000 stars) are above the horizon at any one moment. Since there is a lot of extinction (reduction in bri…ghtness) for stars near the horizon, the actual number you can see is somewhat less, even under the best viewing condition. (MORE)
Answer 1: Hundreds of billions of billions. Updated: As of 2009, it was estimated to be around 10 23 stars in the observable universe. However, it was recently disco…vered that we may have been missing most stars of the red dwarf variety and now it is beginning to look like the 10 23 figure would now have to be tripled. So its about.... 3,000,000,000,000,000,000,000,000 (MORE)
About 6000, under ideal viewing conditions - half of them are above the horizon at any one moment.
NO, only through Microscope
