I think we can assume that there is no real way to redirect the star.
First problem is that there are going to be people who are going to refuse to leave. It's all a gubermint/fen conspiracy, we're not abandoning the 5000 years of our history, not willing to leave to the "barbarians" what they have taken by blood. These are all arguments that would be used against the resetlement of people without even gitting into hot political issues. Then also you wpuld have to screen for people who were willing to build civilization from scratch.
