Distribution of apparent magnitude of stars

Hi all,

I need information about the distribution of the apparent magnitude of the stars - how many stars are brighter than magnitude 0, 1, 2, 3, etc. Googling didn't bring any useful results; maybe you will be luckier than me?

Thanx 🙂

What do you need this for?

The apparent magnitude of stars is mainly a function of distance, the nearer ones are stronger by just proximity, Alpha Centauri is just an ordinary sun sized star that would be pretty much invisible 400 ly away, but 4 ly away and it's very bright. So the distribution by apparent magnitude would just be a log graph on average based on distance.

That's fine, but I want the actual numbers - say, how many stars are brighter than magnitude n for each integer n between 0 and 15.

OK, I just found this:

This is a list of the top 80 odd stars by apparent magnitude:

If you hunt around you should be able to get the information you want from a star catalogue. Try looking here:
