Why do Scientists Believe Pluto is Not a Planet

When we used to be in class 3rd approximately 15 years back, we were taught that there are nine planets in the solar system and we kept on cramming all those nine names including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, but just afterwards when we got promotes to the upper classes and new researches were followed by the concerned authorities, Pluto was considered to be a planet but simply a dwarf planet not included in the list of normal planets.
Why do Scientists Believe Pluto is Not a Planet
Pluto as a Dwarf Plutonic:-
Plutonic refers to the celestial thing that is dwarf. Originally when till 2002 the people kept on studying about nine planets, just then a research was made that depicted that Pluto is a dwarf planet and thus after its name the word plutonic got launched which is used to address dwarf planets. A dwarf planet also orbits the sun just like the other planets do, but the thing of difference is only its size. A dwarf planet is so much small that it cannot clear other objects out of its path.
How Pluto Became A Plutonic:-
Pluto was discovered in 1930 by an astronomer from the United States who named it after the name of a girl and after this period, it became recognized as the ninth and last planet of our galaxy, but it was later on in 2003, when an astronomer saw a new object beyond Pluto and thought he had found a New planet the size of which was somewhat larger than Pluto itself. The new planet was named as “EER-is”. There started a debate afterwards that included the size of a planet to be judged for recognizing it as a planet and thus now Pluto was put in the category of dwarf planets. Pluto and other similar objects in celestial space are now regarded as dwarf celestial bodies.
Why the Name Plutonic:-
As Pluto was the smallest to be considered in the solar system and then as I told you earlier that accidentally another small celestial body got mistakenly discovered, a criterion came into being and it was to decide if something is a planet on the base of its location, shape and size because of which the name plutonic has been given to the small or dwarf planets.
The Universe Is Full Of Un-Answered Questions:-
Just imagine, this universe has got countless galaxies and the milky way, in which there are eight planets including our earth and even the dwarf bodies like Pluto, the area is so large to be explored by a single generation and thus Scientists are trying their best to learn more about it. We have got advancements in technology and new researches are made day by day. The day is not far when we will soon reach even the other galaxies and thus we have to just wait and watch. Universe is full of unanswered questions that can only be answered once researches are made and thus more opportunities need to be created in the field of science and technology.
