Orbital evolution of a widedisk simulation that underwent a Nice model-like instability. The evolution of the semimajor axes, perihelion and aphelion distances of the three giant planets are shown in black, and the semimajor axes of the 19 surviving outer planetesimals in grey (note that one additional planetesimal survived with a = 59 AU). Two terrestrial planets formed in this system, at 0.71 AU (1.4   M_⊕) and 1.76 AU (0.13   M_⊕): accretion was perturbed by the perturbations moderately eccentric inner giant planets at 4.7 AU (0.78   M_J, e oscillates between 0.03 and 0.17) and 7.8 AU (2.4   M_J, e oscillates between 0.06 and 0.1).
