Hereunder is a simualtion of 25 extrasolar systems containing at least 3 extrasolar planets . Data come from the extrasolar planets encyclopedia In each system I've added an Earth like massless planet at 1AU friom the central star , just for reference I've aligned the 25 systems well spaced from each other . You can jump from one system to another by selecting the "Sun" of the new system and center it I had to make some assumptions : the inclination of each system is zero ; angle of perihelion is set to zero ; all planets were set at perihelion as initial value. The systems in this sim are : 47 Uma 55 Cnc 61 Vir Gl 581 Gliese 876 HD 10180 HD 125612 HD 134606 HD 136352 HD 181433 HD 20794 HD 31527 HD 37124 HD 39194 HD 40307 HD 69830 HIP 14810 HIP 57374 HR 8799 Kepler-11 Kepler-9 KOI-730 mu Ara PSR 1257 ups And
