Billiard with asteroids: apply trajectory intelligence and domino effect to move large asteroids through a sequence of small ones.

YAML 來源 想法

There are so many asteroids. To move a large asteroid, like Cruithne to Mars, you don't have to do it directly. Small asteroids could push larger asteroids slightly to collide with even larger ones, until a larger one is cought by a gravity well.

Rather than investing $ to lifting more fuel, it could be invested into getting more information -- surveying the surfaces, masses, spins, etc. of asteroids to make precision collisions.

Inspired by [asteroid to mars] idea.

This may be among the most realistic ways to move planets with small initial amounts of energy. Just have to map the trajectories of small bodies across the solar system.
