Planet ejection

  1. Jan 21, 2006 #1
    It is said that high massive planets can eject small planets in planetary forming systems. I don't understand that since gravitation is supposed to attrack things. Do you know of any article that expains that kind of phenomenum?

    It attracts it, then the smaller planet, not having collided escapes with the same speed relative to the planet, but a new direction which puts it on an escape trajectory. See the explanations in the thread:
