The late stage of solar system formation is characterized by the direct accretion of the planets from hundreds of lunar sized protoplanets. The gravitational interactions between the protoplanets perturb them into crossing orbits resulting in collisions and mergers. We have developed an N-body simulation to model the final stage of planetary formation. Our code integrates the orbits of the protoplanets numerically using a fourth-order Hermite scheme with an individual timestep which is adjusted independently in order to maintain the accuracy of the simulation, and yet minimize the computation time. In this simulation, all collisions are completely inelastic and result in the merger of the protoplanets. We are using this N-body simulation to verify the results of Monte Carlo calculations of late stage planetary growth. Preliminary results are presented for one of these that investigates the effect of a massive proto-Jupiter outside the terrestrial region during the late stage of planetary growth.
