摘要
Early in the history of the Solar System, the giant planets - including Jupiter and Saturn - migrated under gravity into different orbits around the Sun, causing an epoch of chaos and collisions. Radioactive isotopes in asteroids record the thermal imprint of these collisions, and a broad survey of meteorites now constrains the timing of the migration to approximately 11 million years after the Solar System formed.
