Pluto: A Dwarf Planet In Our Solar System

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

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.

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.

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.

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.

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.

Pluto shouldn’t be described and identified or labeled a dwarf planet because it has the same features as other planets, it does everything the other planets do and more, most importantly each planet is different making pluto the same. Pluto should be considered a planet it’s not fair! According to, Charles Q. Choi, Space.com Contributor, Pluto has 5 moons. According to Nine Planets, Pluto has an atmosphere consisting of mainly nitrogen extending to 1,600 km above the surface. According to Business Insider, scientists estimate that smooth patch on Pluto is only about 100 million years old, as

Which is the largest of all dwarf planets? Pluto is a dwarf planet in our solar system and has been given the nickname Xena. Pluto was once considered the ninth main planet from the Sun. Scientists discovered Pluto on February 18, 1930 (history.com). Several objects surround Pluto including Nix (Pluto’s natural satellite) and Hydra (Pluto's outermost satellite) , comets, and the constellations “Teapot”, and “Scorpius”. Pluto is a fascinating planet because of its discoveries and missions, composition, and research.

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

Pluto by far was the least massive planet, with less than 5 percent of the mass of Mercury, the solar system’s next smallest planet. The orbit of Pluto is very flat from a perfect circle. In fact, Pluto spends 20 years of its 248 year orbit closer to Neptune than to the Sun. Pluto’s orbit is not only oblong, it tips more than 17 degrees from the plane of the solar system, a full of 10 degrees more than Mercury’s orbit.

The size also awards it the title of being bigger than Eris, a mini-planet that circles Neptune in the Kuiper Belt.

The present unknow ninth planet was discovered in 1930, pluto is the second smallest planet from the solar system and most massive dwarf planet. Pluto down to the newly created classification of ¨dwarf planet.¨ There are still many objects with similar size and mass to pluto jostling around its orbit. The dwarf planet Pluto is named for the ancient Roman god of the underworld. In Roman mythology, Pluto was the son of Saturn who, with his three brothers, controlled the world: Jupiter controlled the sky, Neptune controlled the sea, and Pluto ruled the underworld.

Known as a dwarf planet, Pluto is in the Kuiper belt, a ring of bodies beyond Neptune. It was the first discovered Kuiper belt object.

Today Pluto is now known as an icy gaseous white dwarf planet and is the second largest white dwarf planet with Eris being the largest. My submission will support my argument that Pluto should not be classified as a Planet or a Small Solar System Body, but a Dwarf Planet as classified in 2006, by the International Astronomical Union. First, the physical characteristics of Pluto support that Pluto has been properly reclassified as a dwarf planet. Pluto's density and size are much smaller than all other planets, as studies have confirmed that Pluto's width is 1582 miles long and the length is 1400 miles long and its mass is less than 0.024% of the planet earth.
