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.
