Should Pluto Be Considered 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).

Indeed, most of the problem is that there is no formal definition of a planet. Furthermore, it is very difficult to invent one that would allow the solar system to contain all nine planets. I suggest that for an object to be classified as a planet, it must embody three characteristics. It must be in orbit around a star (thus removing the larger satellites from contention), it must be too small to generate heat by nuclear

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.

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.

As we spoke about in class Pluto does not really fit into the categories of being a planet, this was one of the major arguments as to why Pluto should not be considered our nineth planet anymore. I believe that it is interesting that some people were trying to then create a classification specifically for Pluto. However, this obviously did not come to be as there must be more than one of something in order for it

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 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.

Once, Pluto was considered the ninth and most distant planet from our sun. Pluto was discovered by an American astronomer name Clyde Tombaugh in 1930. But before being discovered, an American astronomer name Percival Lowell was actually the first to caught hints of Pluto’s existence in 1905. He suggested that there was another world’s gravity that was tugging at the two planets, Neptune and Uranus, from beyond. It turns out that there was another planet, the smallest and ninth planet from the sun, Pluto. The now dwarf planet was named by an 11 year old girl from Oxford, England whose name was Venetia Katharine Douglas Phair or Venetia Burney. The astronomer did predict the planet’s location in 1915, but unfortunately he died without finding

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.

At the end of our Solar System lies a small a small planet, smaller than any of the other planets, Pluto. In 1905, Lowell, an american astronomer, found the force of gravity of some unknown planet that is affect the orbits of Neptune and Uranus. In 1915 he predicted the location of a new planet. Lowell used a telescope to scope the sky where he thought that the planet would be discovered at. However, Lowell died without actually discovering Pluto. In 1930 Clyde W Tombaugh took over Lowell’s research on Pluto. He used predictions made by Lowell and other astronomers and photographed the sky with a more powerful telescope. After he examined the photos he found Pluto. Lowell and Tombaugh's work helped to find the ninth planet in the solar system,

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

First of all, you probably know Pluto fits all but one of the IAU’s, International planet requirements. The original definition of planet was a wanderer, created by the Greeks that watched these planets move for thousands of years (Scientific American). If the world had left that definition, then we would have hundreds of planets in our solar system including Pluto. In fact, we didn 't have an official definition until 2006.This meant that Pluto could no longer be considered a planet since the definition required it to have three characteristics. The IAU decided that in order to qualify as a planet, it had to orbit the Sun, be big enough for gravity to squash it into a round

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,

our solar system, but they are unimportant compared to the nine major planets. In this paper I will discuss the planets and how they are each unique.
