Analysis Of Pluto As A Dwarf Planet

Improved Essays
Ever since 2006, when Pluto was "demoted" to be a dwarf planet, people all over the world have complained about the change. The complaints are based partly on nostalgia; as children, they learned that Pluto was a planet, and they do not like change. However, in this essay, I argue that classifying Pluto as a dwarf planet is justified as the classification is useful; however, its status as a dwarf planet should not indicate that it is not as interesting as the planets. I will discuss, first, the historical context in which Pluto came to be demoted, the respective definitions of planets and dwarf planets, and finally, the usefulness of the classifications that result from these definitions.

The whole debate as to whether Pluto should be considered a planet started when an astronomer from Caltech, Mike Brown, discovered the "tenth planet," Eris. Eris was slightly bigger than

In order to determine whether this is a classification that should be adopted, we must ask: is this classification useful? The requirement that a planet be round is a factor in whether geological and planetary processes can occur, and so is a useful distinction. The requirement that a planet clear other objects of its orbit is, I think, also a useful classification. Studying how different celestial bodies interact with each other is an important part of both muggle and magical astronomy, and so distinguishing bodies based on how they interact with the objects around them is useful. Furthermore, the small number of bodies that can be classified as a planet according to this stricter definition is itself informative. Since so few bodies are planets, it shows that the bodies which do pass all of the criteria are unique in some way. The successful vote of the IAU to take on these definitions also indicates that it is the consensus of experts in the field that this is a useful classification to

    The last dwarf planet is Eris, and it may be the largest. There is enough of a margin in the measurements for Eris to be larger than the current largest dwarf planet Pluto. Eris has only one known moon and was once tested to be the tenth planet in our solar system. I don’t think any decision on whether or not Eris becomes a planet is matters or doesn't. It has reasons to become on but also some why it should stay a dwarf planet.…

    Opinion: Pluto is a Dwarf Planet This astronomical study will define the development of Pluto from being a planet to a “dwarf planet” in the solar system. Pluto is a planet with about 30 to 49 astronomical units away from the sun, and it takes about 5 hours for the light of sun to reach its surface. Pluto also has an orbit of 248 years, which makes the longest orbital time period for a planetary object in the solar system. The mass of Pluto is 1.303±0.003)×1022 kg and the radius of the planet is 0.1863 Earths. The small size of the planet makes it around one-sixth of the size of the moon, which made it the smallest planet in solar system.…

    It is thought that circuitry failure is the reasoning behind these failures (Hunter, 2016). In addition to its “picture-taking” abilities, the Kepler telescope also contains a photometer, which spans a range of four hundred and twenty to nine hundred nanometres (420-900 nm). This measurement goes well beyond the typical optical spectrum, and heightens the machine’s light sensitivity and detection ability (“Kepler Space Telescope”, 2016). Such equipment has allowed for the discovery of the newly-minted “Heartbeat Stars”, and various other phenomena. It is because of all of this advanced that technology that the Kepler telescope remains at the forefront of assisting in astronomical discoveries, and is perhaps one of the greatest scientific instruments ever…

    Basically almost everything is held by gravity in space. Some astronomers believe some galaxies as held by black holes. But is that really the case? The short period of growth of the universe started of as the Big Bang about 13.7 billion years ago. After the Big Bang the universe started to cool of, starting protons and neutrons, hydrogen, helium, lithium and more.…

    Also published in the Christian Science Monitor, Liz Fuller-Wright comments on the Mars rover planning to be launched in 2020. “The budget for Mars 2020 is about $1 billion less than the budget for Curiosity [a rover currently doing geological research of the soil on Mars], coming in at $1.5 billion”. The plan she suggests is to “recycle Curiosity 's design [by] using some of its some spare parts.” (NASA’s Going Bold – On a Budget) With new engineering or research this rover may be able to accomplish its mission within its estimated time. Although NASA has a limited budget, they aren’t the only space agency looking into Mars. An example is SpaceX, who has been testing different rockets that can accurately land back toward the planet.…

    The methane was described as by Michael Mumma as “ephemeral- now you see it, now you don’t.” (Achenbach) However, despite the lack of methane on mars it does not rule out the possibility of other key substances on mars. In fact a mars rover name Curiosity found samples of ground rock that contained water. Nasa stated that the water was "so benign and supportive of life that probably if this water was around and you had been on the planet, you would have been able to drink it”(Spotts). Water is a key building block in life, it supports almost everything on earth as mankind knows it. So if water is a major component that supports life on earth, who is to say it does not or maybe did support life on mars?…

    Introduction to the Pluto system science special issue, published by Elsevier Inc. in 2015, is considered as an academic journal. The first paragraph notice the Pluto in detail. The Pluto orbit in an average 39.44 AU from the Sun and have a high eccentricity, have a radius of 1137km which is much smaller than the Moon. For the article I’m evaluating, it indicate that the Pluto’s aphelion is about 4.6 billion miles (50.13 AU). The diameter is about 1500 miles (2400 km), we can tell it’s about 1200km in radius, which is extraordinary close to the accurate number.…

    The moon is a place that we know little about and very few people are lucky enough to get to experience it in person. Some interesting facts that we know about the moon because of science are that the the moon rotates at 10 miles per hour compared to the earth's rotation of 1000 miles per hour. Only 59% of the moon's surface is visible from earth. From earth, we always see the same side of the moon;…

    Mars’ atmosphere is 1% as dense as Earth’s, which makes it difficult to hold liquid water on Mar’s surface. Furthermore, Jupiter has 66 moons, which are pretty small. Of the 66 moons there are four large moons, known as the Galilean moons. Which scientists are intrigued by because they may have environments that can support life. Lo, Ganymede, and Europa are all in a resonant orbit with one another.…
