How Can Pluto Be Considered A Planet?

Of the more than 1,000 known objects in the Kuiper Belt, 2003 UB313 and Pluto are the largest and second largest (Brown 17-19.) Brown's states a fact of how many objects (nearly 1,000) in the Kuiper Belt are smaller than UB313 and Pluto. They are still considered bigger than what an asteroid is and still be deemed as a planet. “But subsequent study showed that Pluto is puny, barely a quarter the size of our own Moon. And we now know that Planet X never existed, the product of some subtle errors in some century-old mathematical calculations. While the first eight planets all rule their orbits,” (Gaensler 37-39.) Gaensler says in article that Pluto should not have been started as a planet because of subtle errors in some century-old mathematical calculations. Pluto was too small to be considered a planet, and should only have the first eight planets rule their orbits. From these quotes from the two articles, we learn that facts for the Pluto’s size being bigger than what people think. Pluto is basically can be a “continents” because there is large continents while small ones. If Pluto is the second largest object in the Kuiper Belt, it should be considered a planet in our eyes. The article, “Why Pluto had to go”, talks about how the size of the our moon being larger than Pluto. Pluto size doesn’t even compare to our Moon so why should it be consider a planet. I think we can learn that the first eight planets that were the largest in size should be only the ones called

Pluto has a crust believed to be composed mostly of water ice, with a relatively thin layer of nitrogen ice mixed with small fractions of methane and carbon. However, there is no particular scientific reason why this should exclude Pluto from being classified as a planet. It is just as reasonable to claim that all planets must have rocky surfaces, like the terrestrial planets: then Jupiter, Saturn, Uranus and Neptune would have to classified as something other than “planets” (perhaps they would be minor planets?). Alternatively, it could be declared that all

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

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.

Unless the criteria for planets changed Pluto shouldn’t be flipflopping back and forth. This shows that emotions for certain objects, such as Pluto, aren’t exempt from those that make the debatable decisions. Why do peoples’ emotions get in the way of making decisions? Decisions should be based off of facts, not how one feels during one specific time. Looking off of the facts also helps there from being any bias.

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.

The planet needs to be big enough and have enough mass to clear its neighborhood, the purpose behind this is that all planets orbit relatively close to each other so it's important that they clear their space so they do not run into other planets. Pluto is so small, astronomers theorize that Pluto was once one of Neptune's moons. (Science. Howstuffworks 1). Counterargument:

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.

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.

and it has to have cleared it’s orbiting path.pluto fallows the first 2 rules but not the 3rd so pluto can not be considered a planet. All of the other planets follow these rules allowing them to be a planet so pluto only qualifies as a dwarf planet.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, “all” the planets? All across the globe basically everyone says Pluto isn’t a planet. I mean sure it’s not like the others it does strange movements. But isn’t that like humanity? I mean, we don’t look the same, we are all different shapes, sizes colors, we make weird moments, does that make us not human?

Pluto was found by a scientist in 1930. Through that time there was debates over whether this little ball of ice should be not considered a planet. It shouldn't”t be a planet because it does not dominate its neighbors.Also, Pluto’s orbit overlaps Neptune’s orbit That is not acceptable.Another Pluto has a moon a bit bigger than itself .On universe today it states “What does “cleared its neighborhood” mean? As planets form, they become the dominant gravitational body in their orbit in the Solar System…... Pluto is only 0.07 times the mass of the other objects in its orbit. The Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit.” This is saying its too small to be a planet. Also on Starchild, it says “Pluto is usually farthest from the Sun. However, its orbit "crosses" inside of Neptune's orbit for 20 years out of every 248 years. Pluto last crossed inside Neptune's orbit on February 7, 1979, and temporarily became the 8th planet from the Sun.

A planet is defined as an object that orbits the sun, has sufficient mass to be round, or nearly round, is not a satellite (moon) of another object. A planet is also defined that is needs to remove debris and small objects from the area around its orbit. A dwarf planet is defined as an object that meets planetary criteria, except that is has not cleared debris and other small objects from the area around its

Pluto’s orbit is very different from the other planets in the solar system. There are three criterias you have to meet in order to be considered a planet. It has to orbit the Sun, be in the shape of a

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.
