If I'm not mistaken, the Centaurus system is a system with six stars dancing nutzo orbits around each other. Two sets are inside the system and orbiting each other and the 3rd set is running outside of the system orbiting each other at the periphery.
THIS is the reason that it was always considered EXTREMELY unlikely that any of the Centauri stars could support a planet. They'd keep running over each others planets. Maybe not literally but gravitationally at least.
And not to mention the problem of cosmic radition, too. The trip to the moon had the protection of the Van Allen belts, but outside of that...even to Mars...good luck.
