On February 18th, 1930 the dwarf planet known as Pluto was discovered! It was discovered by an astronomer named Clyde Tombaugh and named by an 11-year-old girl. It was the farthest planet and the smallest. However when it was discovered it was named a planet because they did not have much information about it. They assumed it was a planet. It looked like a planet so they thought it was a planet. 76 years after Pluto was discovered on August 24th, 2006 astronomers demoted Pluto from planet status to dwarf planet. Till this day many people still claim Pluto to be a planet. People still do not know the difference between dwarf planets and regular planets and with these characteristics you realize that Pluto should not have been considered a planet …show more content…
There is only one key difference between a planet and a Dwarf Planet. To answer the question of what a dwarf planet is we must realize what a dwarf planet is not. A planet is defined in three ways, 1. It is in orbit around a star, 2. It is spherical, 3. It is not a satellite, 4. It has cleared the neighborhood around its orbit. A dwarf planet must follow steps 1, 2, and 3 however they do not follow number 4. To clear the neighborhood means to clear the area around its orbit. When they were defining a planet this was a major point, which made astronomers determine Pluto to not be a planet. Pluto is not the only dwarf planet; there are four other known dwarf planets. They are Eris, Haumea, Makemake, and Ceres. Ceres was the first dwarf planet that was …show more content…
They do not like to mention how for 76 years they believed this object was a planet when in reality it was just a dwarf planet. Although we are getting new evidence every single day about Pluto it is still extremely hard to make a permanent judgment about. When we thought we knew everything about Pluto 76 years later we found out that it is probably not a planet anymore. After we determined that 9 years later we found out that in may in fact have some evidence that it could be a planet. However when we get new evidence we tend to forget the basics. When it comes down to the basics then a planet must orbit around a star, be spherical, not be a satellite, and clear the neighborhood around its orbit. When you can clear all four of these criterion then you can be labeled a planet. However just because you look like a planet and have features of a planet it does not mean one hundred percent of the time that you will be labeled a planet. As of now Pluto is still a dwarf planet however with new evidence coming to astronomers everyday we should not be surprised if this
