6 0

There are something like 3,000 to 4,000 stars that are bright enough to see with human eyes and no optical equipment.

There are TRILLIONS of them in the part of space that we can see with big telescopes, and we don't know how far the universe keeps going after that.

There may be NO end to it, and then there would be NO end to the number of stars.
