This means that for an eight-planet system, the average difference in mass between planets would be less than 2x rather than the much higher differences seen between Jupiter and Saturn compared to Neptune. This, therefore, means that our solar system, due to its peculiarity in planetary architecture, is uncommon in its ability to have planets migrate to the extent at which they are able to eject high amounts of debris into interstellar space, as the mass difference between the planets would not generate the force required to do so.
This once again points to a peculiarity of our solar system unseen in others, however, while the planet’s temperature peculiarity is based more on physical, though biased evidence, this peculiarity is based upon frameworks which are applicable to all systems within the galaxy without requirement of currently unobtainable measuring systems.
