Asteroid diversity points to a "snow globe" solar system

Our solar system seems like a neat and orderly place, with small, rocky worlds near the Sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed. However, the true history of the solar system is more riotous.
