How many photons do we see per star? Some stars seem brighter than others.  At first thought, I would think that we see more photons from it.  But then I think about how wide of an angle a star is shooting photons in all direction... and how far we are away, and the very very pricise angle needed to hit our eyes.  I think the number of photons being released by a star has to be astronomical even if just 1 or more hit our eyes.

I bet the math is beautiful on how we estimate how many photons that a star releases over a time period.
