This is definitely worth watching. One question though, do you intend to use existing stars or are you making them up on the fly? Also, do you intend to approach "habitable" planets in a realistic way (i.e. stars of the right size and age) or do you intend to wing that as well?

If you're looking for actual data on locations and what not, might I suggest the ISDB (http://www.stellar-database.com/) as a helpful starting point for some good data.
