A record of planet migration in the main asteroid belt
@article{Minton2009ARO, title={A record of planet migration in the main asteroid belt}, author={David A. Minton and Renu Malhotra}, journal={Nature}, year={2009}, volume={457}, pages={1109-1111} }
The main asteroid belt lies between the orbits of Mars and Jupiter, but the region is not uniformly filled with asteroids. There are gaps, known as the Kirkwood gaps, in distinct locations that are associated with orbital resonances with the giant planets; asteroids placed in these locations will follow chaotic orbits and be removed. Here we show that the observed distribution of main belt asteroids does not fill uniformly even those regions that are dynamically stable over the age of the Solar…
