The dynamical structure of the Kuiper Belt provides evidence of orbital migration of the outer planets during the early history of our Solar system. Such migration would have occurred during the late stages of planet formation as a consequence of the scattering and final clearing of the residual planetesimal disk in the outer Solar system. The absence of Kuiper Belt objects (KBOs) in circular or low-eccentricity orbits, and their relative overabundance in the 3:2 orbital resonance with Neptune is best understood as due to a sweeping by orbital mean motion resonances by an outwardly migrating Neptune. The eccentricity distribution of the resonant KBOs provides an estimate for the magnitude of Neptune's migration, Delta a_N~8 AU. Sweeping mean motion and secular resonances also cause inclination excitation which is sensitive to the time scale of migration. Numerical simulations indicate a timescale of ~ 3*E(7) yr for the planet migration/resonance sweeping process to explain the inclination distribution of KBOs.
