In elementary school, I only learned about eight planets with the famous saying of, ‘My Very Excited Mother Just Served Us Nachos.’ So, I was never taught to think Pluto was a planet. I saw that it wasn’t planet on the internet and just went to with the concept. However, I wonder now, why can’t Pluto be a planet? Caltech planetary scientist Mike Brown can explain why Pluto is no longer considered a planet.
I believe that Pluto isn’t a plant since it doesn’t rotate around the sun in a perfect orbit as the others, but Brown said he noticed how Eris was bigger than Pluto, and he wanted to redefine what a planet was. Therefore, he killed Pluto since there are objects bigger than Pluto. He didn’t want to say that there are 20,000 planets out there
Going back to the criteria the three pieces of criteria it needs to meet are, the object must orbit the sun, the object must be a sphere and it must be created and maintained by its own gravitational force, and the object must have a clear path around its orbit of other objects. Pluto does orbit the sun. It does have a spherical shape, but Pluto’s path is not clear, it is crowded with lots of other objects. That proves that Pluto is not a planet because, it only meets two of the three criteria pieces.There are rocks in outer space that are the same size as Pluto! That’s pretty small to be considered a planet. If you look at a comparison of the other planets and Pluto you will see the drastic difference. Pluto is just simply too puny to be a planet. Many people say that it should be continued to be thought of as a planet because it has been that way for a long time and that's how most people know Pluto as, a planet. That doesn’t matter though, just because people are used to it being known as a planet doesn’t mean Pluto should still be considered a planet. Facts clearly show that Pluto is a dwarf planet. There are rocks in outer space that are the same size as Pluto! That’s pretty small to be considered a planet. All in all, Pluto clearly isn’t considered a planet, because it only meets two out of the three criteria pieces to be considered a
My Thesis statement is Phuto was once considered to be a planet but now Pluto is the most famous dwarf planet in our solar system. Pluto is made up of ⅔ of rock and ⅓ of ice. Pluto was discovered by Clyde Tombaugh on January 23, 1930. Pluto is very very cold you can't even imagine how much colder it is than Antarctic.If that happen in Earth the air would turn into snow that's how cold it would be about 230 degrees below zero Celsius. When you want to see Pluto up in the sky you can't even see Pluto with your naked eye. Pluto is very hard to see once you look in the telescope it look a little like a star even with the telescope.
Neil DeGrasse Tyson wrote The Pluto Files: The Rise and Fall of America’s Favorite Planet to examine why Pluto ought not to be considered a planetary body and instead a dwarf planet or Kuiper Belt Object.
Despite Plutos dwarf planet status it still hosts several moons. Its biggest moon Charon is almost as big as Pluto so it was beleived to be a double planet. Also Pluto's moon Charon may have an ocean on it the gravitational force of Pluto to Charon strethces the moons insides warming it enough to possibly have a moon.
Most people my age and older likely grew up learning that Pluto was a planet their whole lives. In elementary we were always taught that Pluto was the ninth, smallest, and farthest planet in our solar system. It seemed odd when the planet was reclassified because you had been taught something for so long and it just changed out of nowhere. Even though Pluto does not meet the requirements and is no longer considered a planet I feel like most people still consider it a planet and have been taught that for most of their lives and it will always be a planet in their minds for as long as they live. The way they keep trying to define what it means to be a planet maybe one day we will be able to call Pluto a planet
Pluto being a planet is a controversial topic all over the world, should Pluto be a planet? Or should we exclude Pluto from being a part of our solar system. Here are three agreements that could be made to support the fact that Pluto should never become a part of our solar system. There are three characteristics that an object in space must have to be classified a planet and there are three characteristics as well to be classified as a dwarf planet, a dwarf planet must be able to orbit the sun, just like all objects in our solar system; a dwarf planet has to be small enough for the mass to not be able to clear its neighborhood; also, the entail shape needs to be round. Now the criteria for a planet is roughly the same as a dwarf planet with the exception of one characteristic.
If Earth circled the sun in Uranus' orbit, it wouldn't be able to clear out its neighborhood and would not qualify as a planet.” Stern Said. Why should pluto be demoted on earth, we don’t demote mammals or animals of their size if we have a tiny mammal we wouldn’t call it a dwarf mammal we would call it a Mammal not a dwarf mammal a regular mammal. Why should space be any any different, Pluto
For the first source, an article called “Is Pluto a Planet”, written by Graham Rax. This article was published by Kalmbach Publishing Company in 1999, on a magazine called ASTRONOMY. It mainly from several point of view to discuss about his opinion: How does the scientist find the Pluto. What the properties does the Pluto has. The Pluto’s neighborhood condition. The definition of the planet. At last it gives a conclusion that
Pluto is beautiful. Whatever its status: planet or not, New Horizons’ recent flight by the littlest “planet” confirmed that the dwarf has a lot of “heart”; and over the next 16 months, images will pour in from New Horizons to an expectant audience. Even the few pictures received thus far have caused “hoorays!” from scientists who have gathered more intel about Pluto than ever before.
Many issues have arisen from the debate whether or not Pluto is a planet. Some astronomers say that Pluto should be classified as a “minor planet” due to its size, physical characteristics, and other factors. On the other hand, some astronomers defend Pluto’s planet status, citing several key features.
Is Pluto A Planet? Is Pluto a planet? Is it not a planet? We are required to decide. Pluto is definitely not a planet as a result of Pluto has the same composition of everything in the Kuiper Belt, doesn't follow all three rules of the IAU and is too miniature to clear other objects and debris out of its path.
The discussion about Pluto’s status in our solar system is still in question. The definition of a planet is changing as society advances and as time passes. We used to believe that Pluto was a planet which orbits the sun, but in a weird way since it’s orbit is quite odd compared to other planets in our solar system. Pluto is different such that, it has five moons and crosses Neptune’s orbit. Not only does it do that, it is quite small in contrast to the other celestial body in our solar system. As society advances, we question the definition of a planet and Pluto’s status in our solar system. Our crave for knowledge and curiosity about what’s around us motivates us to explore the unknown. Our desire to learn more is due to the fact that people
Some argue, why make Pluto into a dwarf planet when everyone knows it as a planet. Scientists found many dwarf planets after Pluto. They were not going keep adding them to the solar system. Eris was discovered after Pluto and later on Makemake, Ceres and more. Pluto's size and condensation fits much better with the dwarf planets.
Astronomers now label Pluto as a “dwarf planet” because it does not meet all of the criteria to be a planet. It is also not alone in its orbit; it is part of a wide group of small-scale objects that have been detected revolving around the Sun beyond Neptune.
To be qualified as a planet and object must orbit a star, is not star-like in that it is undergoing internal nuclear fusion, and has a gravitational force that will allow it to retain a spherical shape. Pluto certainly fulfills these requirements, however, there are Kuiper objects that also meet the same criteria. These objects have been classified as minor planets and have been assigned a numerical designation. Despite all the argument for demoting Pluto to a minor planet, its status has remained the same, even if solely contributed to maintaining historical context.
