From what I read, it's my understanding that this planet doesn't rotate. Half of it is constantly fixed towards it parent star, and the other half is in permanent darkness. That makes one side incredibly hot and the other side freezing. The only place on it that is theoretically habitable is the line between these two climate zones. It also has a 37 day orbit around its star. I would hardly call it earth-like. That comparison probably relates to its size and the fact that it's in the potential life zone of orbit.
Sadly, humans will probably not make it to the stars at the rate we're going. I know many people are hopeful but, unless we solve our energy problems and the way we conduct economy, our society is just going to collapse and go back to an earlier stage again. I have heard it theorized that that is basically what humans have done throughout history... risen and fallen, going from advanced back to primitive conditions again. Until we have a stable global platform from which to start to foster social and material stability, combined with intensive space programs, we are not really going anywhere. Forget about our sun blowing up. We won't be around to see that... either because we evolved into something completely different, we left, or we self-annihilated. Either way, our existence on earth will be brief in cosmic terms.
