That day may not come. Changing the stars is big work, and there's no guarantee we'll develop technology for such a thing.
Besides that, the idea behind astrology is that the rays of the heavenly bodies create energetic changes in the earth's field of energy, the energy we live in and experience as a fish living in water. If the theory is true, then no matter where we go we'll be exposed to these rays - from stars, and from the planets surrounding whatever place we colonize, should we eventually do so.
Are we not also of existence? of stars? of earth? One only needs to change himself to change the cosmos.
