Example of one non-symmetrical satellites distribution around M33 induced by a pericentre passage around M31. The initial conditions for the orbits are the same as those considered for the left panels of Fig. 4. Test-particles in M33 disk are marked in blue, the simulated satellites are in orange, observed HI clouds (possible dark satellites of M33) are shown with open green circles whose sizes are proportional to cloud masses. The red star indicates the position of AndiXXII.
