An example of the initial conditions assumed to exist shortly after the epoch of gas disk dispersal. The terrestrial planet formation zone contains planetary embryos and lower mass planetesimals, while the outer planetesimal belt contains a population of relatively low-mass (compared to the giant planets) bodies that are represented numerically by N equal mass particles. The intermediate zone contains 3 fully-formed giant planets whose spacing is such that they are marginally unstable against dynamical instability.
