The Pluto Files: An Analysis

The International Astronomical Union decided that Pluto was too small to be a planet and created a new category to put it in, dwarf planets. Dwarf Planets are classified as “A) a celestial body that is in orbit around the sun, B) has sufficient mass for it self- gravity to overcome rigid body forces so that is assumes a hydrostatic equilibrium (nearly round) shape, C) has not cleared the neighbourhood around its orbit, and D) is not a satellite”. The criteria for both planets and dwarf planets are very similar, though planets must be able to clear the neighbourhood around its orbit. This basically means that a planet must be able to complete a rotation around the sun without interfering with another planets orbit. Pluto is very close to Neptune so they had a chance to collide into each other. If you look at a visual it is clear that there orbital rotation paths intersect with each other at two locations. This is another reason why Pluto is no longer considered a planet.

Every planet in the Universe has it’s own place including Earth. Earth is located inside the galaxy called the Milky Way, which includes millions of planets, including the solar system. Therefore up above Earth, in space, is the solar system in which the Earth resigns. This solar system consists of eight planets, one sun and one dwarf planet. Each of the planets or in Pluto’s case, a dwarf planet, are different sizes and have a different distance from the Sun. Earth, for example is one of the smaller planets in the solar system but bigger than Mars, Mercury and Venus. Mars is about two times smaller than Earth but Jupiter, Saturn, Uranus and Neptune are bigger than Earth. Since Pluto is a dwarf planet it is also smaller than Earth. Interestingly

*Some would say pluto is a planet, But there are lots of reasons why pluto is considered a dwarf planet. First off, By definition “a planet is a sphere that orbits the sun, clearing the region as it goes.” Though Pluto does orbit the sun it is still not a planet because it’s so small. According to Nasa.gov “It’s so small it can’t clear other objects out of it’s path.”

Pluto is scientifically classified as a dwarf planet, which is a surprisingly big category considering there

Additionally, another reason for the demotion of the Pluto was its size; on the one hand, the reading states Pluto’s reclassification as a dwarf planet honors the fact that science is about new discoveries. On the other hand, the lecture holds as not valid the definition

Due to some of Pluto’s various characteristics, this icy dwarf planet, and other dwarf planets are not considered regular planets, such as Earth. These reasons also make other dwarf planets, like Eris, Haumea, Ceres, and Makemake, outliers, when compared to the general eight planets. Astronomers predict that there are possibly hundreds of dwarf planets that surpass the Kuiper Belt, just waiting to be discovered. There are three rules, making a planet, a planet. These include, the planet is round, it orbits around the sun, and it has cleared the neighborhood of its orbit. Pluto only follows the first two rules therefore, Pluto is no longer called a planet, just a dwarf planet.

We know that each planet has its own orbit. However Pluto was seen “having an affair” with Neptune’s orbit last February 7, 1979 and left 20 years later on February 11, 1999. This happened because Pluto’s orbit doesn’t lie in the same plane as the eight planets, but it is inclined at an angle of 17°. Because of this, every 20 out of the 248 years of Pluto’s revolution, it is actually closer to the sun than Neptune. I guess you could say Pluto really went “out of line”

Starting off with no secrets, Yaeger tells the viewer of this article what Will Grundy of Lowell Observatory in Flagstaff, Ariz believes about Pluto. Will Grundy shares an unpopular opinion on Pluto which is stated in the magazine, “Pluto is a Planet” (Page 4), and he seeks to prove this to everyone. Now, why would Pluto not be a planet? The article addresses this question excellently, as explained by the provided definition of a planet originally, “The idea of a planet as a roundish, rocky or gaseous body that orbits the sun stuck, until 2006.” Although, the International Astronomical Union (IAU) changed this definition in exchange for a more narrow criteria for a ‘planet’, this is what led to Pluto being downgraded to a dwarf planet because, unlike its other orbiting masses, Pluto doesn’t consume or fling any objects into space.

Pluto was officially discovered by Clyde Tombaugh (http://www.achievement.org/autodoc/page/tom0bio-1) on February 18th, 1930. It resides in the farthest cluster of objects in our solar system known as the Kuiper Belt. In these 85 years that we have known of Pluto, it has yet to make one whole revolution around the sun. Not only is Pluto’s journey around Sol incredibly massive, New Horizons’ trek to the now dwarf planet is just as impressively expansive. Measuring in at around 3 billion miles

Pluto is a Plutoid in the solar system located beyond the orbit of Neptune in the Kuiper belt. It is distant more than 6 billion miles from the sun. Pluto’s history will be examined from its discovery and naming to its recent classification. The planetoid’s orbit will be surveyed as it passes inside and out of Neptune’s orbit. Charon, Pluto’s largest satellite, will be discussed as a possible binary planetoid and the four smaller satellites. Pluto’s composition will be studied from its thin atmosphere to its core. Finally, the significance of several theories of Pluto’s place in the solar system will be analyzed.

In the article "Pluto not a Planet, Astronomers Rule" from National Geographic it states, "a full fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit." (National Geographic). Pluto does not meet these requirements therefore it should not be considered a planet. Pluto does not dominate its neighborhood. Pluto's orbit contains many other objects. Pluto is too small, and does not travel fast enough. Pluto does not meet the requirements to be considered a planet, so it was demoted to a dwarf planet. Pluto did deserve to be demoted, and it should not be considered a planet.

Today I would like to inform you about artificial and natural flavorings. Although they may seem different, one healthier than other; they are truly the same thing. I firmly believe awareness of artificial and natural flavorings in food is a good idea as the FDA, or Food and Drug Administration, does not require that all flavors in food be listed one by one. In fact, when your breakfast cereal says flavors, it could mean one flavor or it could mean seven. So, let’s take a look at what artificial and natural flavors are and what the FDA says they must contain to be labeled under one or the other title, how they are made, the possible health risks they can pose, and lastly, we will look at a company many of you may never have heard about, the Flavor and Extract Manufactures Association.

Through astronomy 101, I have learned many different and new things that I never knew before, but one of the class lectures that interest me the most was finding out about why Pluto isn’t classified as a planet anymore, and what are asteroids and comets. Throughout my elementary, middle, and maybe high school days I always thought there were nine planets. I learned that Pluto isn’t classified as a planet anymore because of its small size, where there are moons and asteroids around it that are larger than Pluto. I also learned that Pluto’s orbit is more elliptical than circular causing its orbit to cross Neptune. Because there were other objects that are larger, and maybe even similar to Pluto, we were able to classify and see what comets and

In recent years it has been found that there are many planets other that are larger than Pluto. This finding led the scientist in dilemma whether it should be reclassified or not. Moreover it is been identified that the Planet is smaller than the earth’s moon. To overcome this problem the ICU organization went for voting. This poll was done during the international scientist meet. As a result the Pluto was scrolled out from the planet list and is now represented as a dwarf planet. This was a

From the time Clyde W. Tombaugh first discovered Pluto in 1930, it was viewed as an oddball planet leading up to its reclassification in 2006. For decades, Pluto was once used as a benchmark for the outer reach and size of our solar system. In recent years, new discoveries of celestial bodies within the vicinity of Pluto’s orbit have challenged its planetary status. The debate over Pluto’s classification was discussed throughout several media and news articles, leading to serious controversy amongst astronomers and the decision as to whether or not Pluto should be categorized as one of the planets in our solar system.
