Pluto Essay

When I was a child, I vividly remembered an anime series called Sailor Moon. The plot revolved around nine superheroes who were named after the nine planets of the solar system. As a child, I could recall the theme song of the series, which begins with “She is the one named Sailor, Sailor Venus, Sailor Mercury, Sailor Mars, Sailor Jupiter,...She is the one named Sailor Moon.” One day, my sister came up to me and told me that Pluto was no longer a planet. When she told me I could not believe my ears, they took out Pluto from the solar system. Recalling the moment that Pluto was removed as planet, I questioned what criteria decided the removal of it from the solar system. At the same time, these changes are made by scientists who believe it does

We continue to search in the universe to find intelligent life that may exist on Mars. However, it is not necessary to find life out in the universe as there are still many mysteries that surrounds humans. For example, the diseases that we are still not immune to still need vaccines and cancer that still kills millions still needs a cure. Nevertheless, these discoveries paved the way for us to understand why there is such a huge and extraordinarily universe out there. In addition, classification assist our understanding of the universe as it simplifies the complexity of the universe. At the same time, without classification, there would be no possible way to talk about these objects or things. According to Tom Hothem’s lecture, classification allows us to interpret what we know and if we cannot talk about then it would impossible to classify whatever we are talking about. This reveals that everything we know is classified and if there were no classification then we would not know how to address and classify information to others. However, classification is not absolute and exclusive, as what we know today may have evolved or changed from the past (Hothem, Lecture). In other words, classification is not a perfect system and may have some flaws that are attached when classifying objects, things, or

Some issues that may arise are if the term meant to describe such object, or the term does not describe what we could learn from the object. The reason is that science is always evolving as new perspectives are constantly in a battle with new information about the universe and life. For instance, the term “planet” comes into question as there were several controversies about the planet called Pluto. The main issue was that Pluto is no longer considered the ninth planet of the solar system. According to the movie, The Pluto Files, it revealed that the classification term “planet” was an issue concerning Pluto not being a planet. It no longer represented a planet as it lacked the criteria that fit the other eight planets. Pluto compared to other planets was just too small, even with the comparison of Mercury, it was still considered too small (The Pluto Files). At the same time, Pluto neither qualifies the description of a terrestrial or giant planet, eventually leading its removal for the planets of the solar system (The Pluto Files). This explains that there is a criteria that is unknown to us and it decides whether or not Pluto is a planet or not. This eventually leads to several individuals to feel it was wrong to remove Pluto as planet as many grew up thinking it was the 9th planet of the solar system (The Pluto
