* It depends on where you are: Light pollution from cities makes it much harder to see stars. In a truly dark sky, you might see thousands.

* Human eyesight limits: Even with perfect conditions, our eyes can only see a limited number of stars.

* "Visible" is subjective: Do we mean just with the naked eye, or with telescopes?

Generally, under ideal conditions, a person with good eyesight might see around 2,000 to 2,500 stars at any given time. However, that's just a small fraction of the billions of stars in our galaxy alone.
