Why Pluto Should Reclaim Its Place As 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).

Pluto is unlike the other planets in that it has an icy surface instead of a rocky surface, like the inner 4 (terrestrial) planets, or a deep atmosphere, like the next 4 (gas giant) planets.

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

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.

In August 2006 pluto was downgraded to a dwarf planet and it is still considered to not be a planet. Do you think it should be considered a planet? Pluto should not be considered a planet in my opinion.

Pluto should be considered a planet. According to Alan Stern a planetary scientist at the Southwest Research Institute "No object in the solar system has entirely cleared its zone." so that means the third rule rules out all the planets. It’s consider a planet. “The farther away a planet is from the sun, the bigger it needs to be in order to clear its zone.

Outer space is a realm of new discoveries and possibilities. There is one particular planet in our solar system that is brimming with these possibilities. However, for nine years it has not actually been considered a planet. The “dwarf planet”, Pluto, has been overlooked and misrepresented in astronomy and planetary science. Since being demoted from planet status to dwarf planet status, little Pluto has raised some big questions about what defines a planet and what does not. In this paper, I will attempt to persuade you that Pluto should be promoted back to its original planet status. First, I will give you a brief history of Pluto, from its discovery to what prompted its reclassification. Next, I will explain the definition of a planet as given by the International Astronomical Union (IAU) and the definition’s flaws. Finally, I will discuss the recent discoveries of the New Horizons mission and how these new discoveries should lead to the reclassification of Pluto to its original planet status.

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.

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

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.

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

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.

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
