Accumulation of Terrestrial and Outer Planets

Theoretical models of planetary accretion are tested against three major observational results from space exploration.These include (a) the late heavy bombardment event,(b) the mega-impact effects,and (c) the orbital configuration of the Kuiper belt objects.It is shown that these dynamical processes and orbital structures characteristic of the Solar System history can be fitted into a consistent scenario with the accretion of Uranus and Neptune acting as the driving mechanism.
