Why Pluto Become A Planet

Pluto is not considered a planet because it does not meet all the criteria of a full-sized planet. The three criteria are: it has to be in orbit around the sun, it has to have a sufficient mass to assume a nearly round shape or hydrostatic equilibrium, and it has to clear the neighbourhood around its orbit. Pluto only meets two of these criteria. It has not yet cleared its neighborhood, meaning that its gravity has not cleared the space around it. In addition to this, Pluto shares its orbital neighborhood with Kuiper Belt Objects. The Kuiper Belt is a circumstellar disc in the Solar System which is beyond the planets. Therefore, Pluto is considered dwarf planet rather than a planet..

Pluto still needs according to the International Astronomical Union to be able to clear debris from its orbit (Howell). This was Pluto’s downfall, Pluto was too small to be able to clear debris from its orbit. This debunked Pluto as a planet's taking away the planetary status of the ninth planet in our solar system. However, with Pluto meeting three out of the four criteria for keeping its planetary status astronomers classified Pluto as a dwarf planet now (May).

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.

Pluto isn’t a planet for many reasons the main one being, it only follows two of the three criteria of being a planet. According to the article “Pluto: Planet or not?”, for Pluto to be a planet it needs to meet three pieces of criteria. In the article “Pluto: Planet or not?” it states that “Pluto meets two of these three criteria.” Therefore, Pluto should not be considered a planet because, it doesn't meet the criteria it needs to. Many scientist would agree that Pluto is considered a dwarf planet. “Pluto is a dwarf planet” Christensen wrote. It’s just plain and simple, Pluto is a dwarf planet, no doubt about it. There shouldn’t be any confusion about whether Pluto should be considered or not for many reasons. If it doesn’t meet all three

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

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.

Did you know Pluto’s not a planet? Pluto is a dwarf planet. The astronomers are going to find out how Pluto became a dwarf planet.

Should there be eight or nine planets in the solar system? Some. people agree that Pluto should become a planet, but researchers and scientists know better. An example of this is that Pluto only two of the three rules to be classified as a planet. Scientists including International Astronomical Union’s president and astronomer Mike Brown have gladly accepted this idea and even have evidence to support it. Third, people already have a hard time learning all the planets in our solar system, we would have to make all the celestial bodies in the Kuiper belt planets. It is right that Pluto is not considered a planet, and it never should be one either.

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.

Many may urge that Pluto should be considered a planet for it has similar characteristics as the planets of the Solar System; however, others still believe that Pluto should not be considered a planet because of its slight differences and conditions that are not matched.

Pluto should be given the title “planet” for a number of reasons. Pluto was classified as a planet in 1930 until the International Astronomical Union altered the definition of a "planet" and stripped Pluto of the title. Some Astronomers say the International Astronomical Union’s planet definition is fundamentally amiss. The new definition requires that a planet has to gravitationally clear its orbit. What about the Trojan asteroids at Jupiter? What about space dust? That rule could dwindle the number of planets to zero. David Aguilar of the Harvard-Smithsonian Center for Astrophysics asserts, “If we can adjust the definition of planet, just slightly, then Pluto can be included in our solar system.” Most astronomers say Pluto is too small,

Are you familiar with the latest news that Pluto is no longer a planet; that it now has dwarf planetary status and essentially a celestial body of ice? How about the New Horizons mission to Pluto to discover more about its surroundings and environment? Perhaps you heard about these through social media, such as a shared post from a friend on Facebook, or alternatively through scientific journals and articles. Pluto’s planetary status was decided by the International Astronomical Union (further referred to as IAU) that met in Prague in 2006. They came up with a list of criteria that a celestial body needed to meet in order to be considered a planet. The first criterion is that it has to be orbiting around the Sun; the second, it has to be heavy enough for its gravity to overcome external forces so that it has a round shape, and lastly, it has to have gravitational dominance in order to clear its neighborhood of other celestial bodies in its orbit. Pluto fails to accomplish the last criterion of clearing its neighborhood because Pluto shares an environment that consists of numerous celestial bodies which make up Kuiper’s Belt.

In the past the definition of a planet in space was a body that orbits a star, such as the sun, that reflects the star’s light and is larger than an asteroid. This is until new research by new technologies allowed us to learn more and change the definition of a planet. This new information changed the fact that Pluto is no longer a planet, but a dwarf. Dwarfs may confuse many people because it is hard to tell it apart from a planet.

“Pluto” was the supposed ninth planet of our solar system, unfortunately discovered by Clide Tombaugh. The name of the newly found celestial object was chosen by a small girl from, the best nation in the world, Britain. The apparent demon worshiper chose the name Pluto, after the Roman god of the underworld. Pluto held the status of a planet until 2006 when the IAU declared it a dwarf planet. Despite the IAUs categorization of Pluto as a dwarf planet, devoted fans of “Disney”, conspiracy theorists, and malevolent Pluto-huggers alike reject the prospect.
