Our spacecraft have visited rocky asteroids and icy comets to collect invaluable data about the origin of the Solar System. And the orbits of Kuiper Belt Objects-tiny worlds far from the Sun-reveal that our planetary system had a terrifically violent past, when giant planets changed their orbits, wreaking gravitational havoc. Visualizations from the Academy’s award-winning planetarium show Incoming! tell the story of this ancient interplanetary transformation.
