Conclusion
In conclusion, the assertion that the planetary system that Earth is a
part of is typical of other planetary systems is not entirely backed by
the currently discovered catalog of exo-planets, nor the expected models
of planetary system architecture within the galaxy. The exo-planets
currently discovered display a very low rate of existence far enough
away from their star to be able to disrupt the orbits of objects that
have high amounts of Nitrogen ice. This does not even take into account
the greenhouse effect, which would serve to raise the calculated
temperatures of these exoplanets even higher. Of course, it is
understood that this collected physical evidence is not an entirely
accurate depiction of the degree to which exoplanets exist within the
range that Nitrogen ice freezes. This is because the methods used to
confirm the presence of exoplanets are more easily able to pick up on
planets closer to their stars, and more exposed to their heat. This
physical evidence, therefore, is not meant as irrefutable evidence that
N2 ice-disrupting planets are extremely rare, instead, it is meant to
display the fact that there is simply very limited contemporary evidence
suggesting that such planets exist to a high degree. Framework-based
evidence regarding the lessened probability of solar systems
architecturally similar to ours existing is also able to display the
unlikeliness of planets like Neptune being able to migrate to the degree
that they did away from the sun, as that migration was based on the high
mass differences between Neptune and the two gas giants, Jupiter and
Saturn. Due to the fact that “similar” systems are the most common
system, where all planets are highly close to each other in mass, this
level of difference would be unlikely to occur in most other planet
groups, meaning the migration of planets like Neptune would not occur to
the degree that it did in our system. This means exo-plutoids would be
less affected by that shift, further pointing to the fact that the rate
at which our system produces nitrogen icebergs is much higher
comparatively. Although this study has provided evidence to weaken the
applicability of the Nitrogen iceberg model of ‘Oumuamua, it should
still be noted that the Nitrogen ice model is still one of the better
models for the structure of ‘Oumuamua. It is able to explain all the
strange properties of the object and its generation is still possible
and based on much known evidence. This study has, however, proven that
if the Nitrogen model of ‘Oumuamua is correct, then, based on current
knowledge of planetary systems, the passing of ‘Oumuamua through our
solar system was a very rare occurrence.
