Evidence for Asteroid Scattering and Distal Solar System Solids From Meteorite Paleomagnetism
International audience Asteroid-sized bodies are predicted to have been scattered throughout the solar system following gravitational interactions with the giant planets. This process could have delivered water-rich small bodies to the inner solar system. However, evidence from the meteorite record...
