Pluto: Not Considered A Planet

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.

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.

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

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

Why Pluto Should be a Planet I think that pluto should be considered a planet. Was pluto not a planet once before? Why are literal balls of gas considered planets? Who gets to decide what “too small” actually means?

Secondly,what is pluto,a planet,a planet oid or a comet? The outward-bound voyager one and two spacecraft were both launched in 1977,which started the drama about Pluto. Pluto is twice the size of Ceres and the largest known asteroid.

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

Pluto is recognised by the International Astronomical Union (IAU) as a dwarf planet for it doesn't match the third condition of what defines a planet. IAU proposed three conditions to becoming a planet. The first condition being: (a) is in orbit around the Sun; the second condition being: (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape; the third condition, in which Pluto has not met the standards to, being:(c) has cleared the neighbourhood around its orbit. Pluto doesn’t meet the standards to the final condition as Pluto follows the orbit path of some asteroid-like objects in space and are surrounded with these objects. If people were to ignore the third condition and recognise Pluto

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.

When looking at whether Pluto should be a planet a consideration must be made of if it meets certain qualifications. We saw in the qualifications in the latest chapter, and the biggest one that takes Pluto out of the planet discussion. The qualification that it must be able to clear its own orbit. Which Pluto does not do that at the moment, and that is why it should not be considered a planet. That is the reason it is called a dwarf planet, even though it orbits the sun. Furthermore, when Pluto is close to the sun it is still billions of miles away. (Dunbar). When you look at a lot of the figures that are considered planets they have a lot of the features that Pluto does not have. Mainly in sharing the Kuiper belt with

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.

Pluto is the ninth planet in Earth's solar system. However, throughout the years, Pluto has had many differing views on it. Some believe that it isn't a planet at all, since it does not meet all 3 classifications of a planet (Williams Dwarf). On the other hand many scientists do still classify Pluto as a planet. Looking past all of the controversy, Pluto still has a remarkable history in astronomy.

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.
