Thanks! Oh, I see... Proxima Centauri is 4.2 light years away, and Alpha Centauri, which is a binary star, is 4.3 light years away...

The question is, which one does Centauri Prime orbit around? ... OK, it seems that it's neither. Centauri Prime is the third planet orbiting the star Centauris, which is about 70 light years away from Sol.

The inventor of the warp drive is Zephram Cochrane but is he from Alpha Centauri, or is he from Earth...this must be one of those Star Trek inconsistencies.
