How many planets and species are there in Star Wars?

Is their an official count of how many worlds there are in the Star Wars verse, and species, that have been so far named. Apparently in the Star Wars Universe there are 20+ Million, so was wondering how many of them had bee described so far, aka how much free slots do future creators have to work with..

Eh, I don't think anyone has gone through and counted them yet. There's just so many. Although, with 20+ million I doubt the creators will run out of "free slots" anytime soon.

Impossible to give an approximate number.
