2. Hit preset and choose "Earth and Sun". Place four Jupiter size
masses at Y = 0 and X = .8 AU, Y = 0 and X = 1.2 AU, Y = 0 and X = 1.6 AU
and, finally, Y = 0 and X = 5 AU in a line extending outward from the
star . Describe how the system evolves for 100 years. Repeat this
problem but now put the Jupiter size objects at Y = 0 and X = 3.8 AU, Y =
0 and X = 4.2 AU, Y = 0 and x = 4.6 AU and, finally, Y = 0 and X =
5 AU. Watch the system for another 100 years. Do planetary
interactions appear stronger or weaker when the planets are farther from the
star?
