Orbital parameters of planets (blue spots) and 141864 asteroids (red fuzz) at 1 Gyr after the start of the simulation. The various curves are described in Fig. 1. The size of each blue point is proportional to the mass of the planet it represents. The two black curves indicate the pericenter distances associated with these minimum and maximum initial orbital separations, indicating the limits of the conveyor belt. The minor bodies are presented as small red points. In Fig. 1 we present the initial conditions, and explain the terminology.
