Pluto Dwarf 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 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

In the outer limits of our solar system there is a planet unlike any other, Pluto. Pluto was discovered in February of 1930 by an American astronomer, Clyde Tombaugh. It is the only planet to have been discovered by an American. All though we have known of the existence of Pluto for over thirty years now, there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto, Adding to the obscurity of this strange planet is that the capability to send spacecraft such distances has never been achieved. Through the wonders of science and astronomy, there are many things that can be determined, concluded, and hypothesized about this obscure planet.

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.

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.

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 belongs with Jupiter, Saturn, Uranus, and Neptune, or the outer planets. In our solar system, there are two groups of planets called the inner planets, and the outer planets. The inner planets are the first four planets before the asteroid belt, while the outer planets are the ones after the asteroid belt. The asteroid belt is a region of space the orbits of Mars and Jupiter, which probably contains million of asteroids. It is where most of the asteroids in our solar system are found orbiting the sun. Although Pluto was a part of the outer planets, it was the only known planet that orbits mostly in the Kuiper belt. Beyond Neptune is a region full of icy bodies, known as the Kuiper belt. This is what made Pluto stands out, not to mention that it’s also a lot smaller than the other outer planets. This got some astronomers thinking about whether or not Pluto should really be considered a

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.

The New Horizons space mission taught astronomers a lot about Pluto that cannot be seen with any telescope on Earth. For example, “this fascinating world has blue skies, spinning moons, …. And it snows - but the snow is red” (“Solar System Exploration: Pluto: In Depth.”). In addition to this, astronomers also discovered that Pluto had more moons than they originally thought.

NASA’s New Horizons spacecraft has snapped the first ever color photograph of Pluto. The image, shown below, may be a bit blurry, but you can expect more detailed images to emerge as the spacecraft gets closer to the lonely planet on the edge of the Solar System. New Horizons also caught Charon, a moon, in the photograph of Pluto.

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.

Finally, some fun facts about Pluto. Pluto is made of 70% rock and 30% water and ice. That leads to the condition that it is very cold. Did you know that Pluto

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,

In elementary school, I only learned about eight planets with the famous saying of, ‘My Very Excited Mother Just Served Us Nachos.’ So, I was never taught to think Pluto was a planet. I saw that it wasn’t planet on the internet and just went to with the concept. However, I wonder now, why can’t Pluto be a planet? Caltech planetary scientist Mike Brown can explain why Pluto is no longer considered a planet.
