Should Pluto be a Planet?

In 1930 Clyde W. Tombaugh at the Lowell Observatory in Flagstaff, Arizona discovered the planet Pluto. After serving 76 long years as the ninth planet in our solar system, Pluto was controversially demoted to a dwarf planet in 2006. This has raised many debates on whether Pluto was categorized unfairly or not. Astronomers from both sides of the debate have legitimite arguments making it tough to decide whether Pluto should be classified as a planet or a dwarf planet.
Pluto’s title as a planet was questioned when Mike Brown, Professor of Planetary Astronomy at the California Institute of Technology discovered an object in 2005 that was further out than the orbit of Pluto. The object was also 25% more massive than Pluto. This object was later named Eris. It is located along with Pluto in the Kuiper Belt. There are plenty of other mysterious objects located in the Kuiper Belt that are more or less the same size as Pluto and Eris. This troubled the International Astronomical Union because this meant that there are tens to hundreds of objects that could very soon be known as planets. There are approximately more than 1,000 objects composed of the same icy mixture located in the Kuiper Belt. Many astronomers, scientists, and the International Astronomical Union felt uncomfortable with the fact that there are hundreds of objects in our solar system that have a strong possibility of becoming planets.
To avoid the feeling of skepticism the International Astronomical Union redefined a planet as “A body that circles the sun without being some other object’s satellite, is large enough to be rounded by its own gravity (but not so big that it begins to undergo nuclear fusion, like a star) and has ‘cleared its neighborhood’ of most other orbiting bodies.” According to Stern, Alan interviewed by Mike Wall “Fighting for Pluto's Planet…...

Revenge of Pluto

...Revenge of Pluto I usually don’t have the habit of waking up early in the morning. But there was somebody on the verge of breaking my door if I did not wake up and open the door myself. The sun was just rising and I could not help but think, when was the last time I woke up so early. The person who was knocking my door wanted to interview me and with good reason. He was from one of those crazy institutions which believed that aliens exist. I actually never saw anybody getting so excited to see me, not even my parents. The reason for him coming was that my warnings had come true. This very morning some eminent scientists were kidnapped, with no trace whatsoever. What was interesting was the fact that these were the same scientists who had got Pluto stripped of its status as a planet. And I had been warning people that the people of Pluto were unhappy at Earth’s condescending attitude. How did I come to know about this?? I have a ham radio, which turned out to be no ordinary ham radio. I was able to intercept signals from somebody from Jupiter. At first I thought I was being taken for a ride, but later realized that it was no joke. What made me realize that was the fact that I was not able to trace the signals to any location on earth. But what reaffirmed the fact was that the alien told that people of Jupiter have winged blue creatures called Ihit, which on interpreting signals from any person could tell about him. And he was spot on about me – everything about me...

Planet Neptune

...Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Neptune is 17 times the mass of Earth and is somewhat more massive than its near-twin Uranus, which is 15 times the mass of Earth but not as dense.[12] On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth–Sun distance. Named for the Roman god of the sea, its astronomical symbol is ♆, a stylised version of the god Neptune's trident. Neptune was the first planet found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus ledAlexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed on 23 September 1846[1] by Johann Galle within a degree of the position predicted by Urbain Le Verrier, and its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining 12 moons were located telescopically until the 20th century. Neptune has been visited by only one spacecraft, Voyager 2, which flew by the planet on 25 August 1989. Neptune is similar in composition to Uranus, and both have compositions which differ from those of the larger gas giants, Jupiter and Saturn. Neptune's atmosphere, while similar to Jupiter's and Saturn's in that it is composed primarily of hydrogen and helium, along with traces ofhydrocarbons and possibly nitrogen,......

The Blue Planet

...THE BLUE PLANET James E. Mack Dr. Claybon Upon my arrival to “The Blue Planet” I could see that the inhabitants were advanced in their own ways. Large groups of people worked together to maintain their own personal societies. Although all the members of each group shared culture, not everyone shared the same religion. Without communicating to the inhabitants it would seem as though they didn’t have a specific religion. Various groups perform their own practices. While some groups gather in beautiful buildings and listen to one read from a book, others kneel in front of decorative statues, close their eyes and mumble to themselves. It seems that the creatures of “The Blue Planet” try to build a variety of moral systems for its inhabitants to abide by. Religion can be assumed to be the foundation of each system. Citizens are expected to follow guidelines similar to ones taught by religion, guidelines which help everyone co-exist with no major problems. Unfortunately though, as I traveled along the much larger areas I noticed that regardless of the moral systems instilled to govern them there was still a great amount of crime, poverty, and worst of all selfishness. In the larger parts of this planet an individual somehow prospers from the downfall of others, instead of working together for the improvement of the whole. At first I thought this aspect must be missing from their religion, to help a fellow being. Or it can simply be determined that religion is not as......

Lab 1 - Planets and Scales

...Section ASTR101-0AM Overview ? Become familiar with the scale of the planets vs. their distances. ? Get an overview of the solar system. ? 50 points are possible Introduction It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same factor, we retain the meaningful information about relative distances between objects. This is exactly the same principle employed by map makers, so that they can fit Texas, onto a book page. General Overview Questions: A. The definition of a planet was changed in 2006. Using your textbook and the webpage resource listed below in number 1: Discuss what the characteristics of a planet are and how this new criteria declassified Pluto. B.

...Planetary geology This astronomical field examines the assemblage of planets, moons, dwarf planets, comets, asteroids, and other bodies orbiting the Sun, as well as extrasolar planets. The solar system has been relatively well-studied, initially through telescopes and then later by spacecraft. This has provided a good overall understanding of the formation and evolution of this planetary system, although many new discoveries are still being made.[50] The black spot at the top is a dust devil climbing a crater wall on Mars. This moving, swirling column of Martian atmosphere (comparable to a terrestrial tornado) created the long, dark streak. NASA image. The solar system is subdivided into the inner planets, the asteroid belt, and the outer planets. The inner terrestrial planets consist of Mercury, Venus, Earth, and Mars. The outer gas giant planets are Jupiter, Saturn, Uranus, and Neptune.[51] Beyond Neptune lies the Kuiper Belt, and finally the Oort Cloud, which may extend as far as a light-year. The planets were formed in the protoplanetary disk that surrounded the early Sun. Through a process that included gravitational attraction, collision, and accretion, the disk formed clumps of matter that, with time, became protoplanets. The radiation pressure of the solar wind then expelled most of the unaccreted matter, and only those planets with sufficient mass retained their gaseous atmosphere. The planets continued to sweep up, or eject, the remaining matter during a......

...PLANETS By Reanna Hinson The purpose of my project and essay is to familiarize ourselves with the different planets within our own solar system. I will present different, unique and amazing facts about each the eight planets. My project also displays a colored example of what each planet appears to look like as well as statistical information. Mercury, Venus, Earth, and Mars, are called the terrestrial planets because they have solid rocky surfaces. Jupiter, Saturn, Uranus, and Neptune and are called gas giants. Earth is the only planet of the eight that has life forms as we know them. All other planets have extreme conditions such as temperatures, atmospheres and weather that make life as we know it impossible to exist, but we still keep looking for alien signs of life. Mercury Mercury is a small planet that spins very slowly in orbit around the sun. It is the planet closest to the sun and has extreme temperature changes. During the day the temperature can soar to 870° Fahrenheit and at night time down to -300° Fahrenheit. Mercury has no moons and a very small and weak atmosphere because the Sun’s solar winds have blown it away. This causes very little to no air on Mercury. Venus Venus and Earth are just about the same size, but Venus always has a thick cloud cover making it impossible to see the surface of the planet, and traps a lot of the Sun’s heat making it the hottest average temperature of all the planets. The average temperature is 850°......

Pluto in Orpheus Versus Pluto in Sir Orfeo

...The author of Sir Orfeo changes the character Pluto because the original representation on Orpheus poem contradicts his Christian believes. If we look in the definition of Pluto, it means Rich Father), in Roman religion, god of the infernal regions, the equivalent of the Greek Hades (q.v.), or Pluto (Rich One). Also known to the Romans as Orcus, he was believed to be the brother of Jupiter and was greatly feared. (Encyclopedia Britannica) In the original poem of Orpheus Pluto is presented as the god of the underworld. For the Christianity is only one god. The following paper will point some of the significant contradiction that we can find in the character Pluto in the two poems. There are too many things in the original character of Pluto that contradict the Christian believes. One of these aspects is the representation of Pluto as all-powerful god. When Orpheus travel to the underworld to rescue his wife He tells Pluto and Proserpine: “ oh deities of the underworld, to whom all we must live must come, hear my words, for they are true” (Orpheus)this is a contradiction for the Christianity that believes that Jesus Christ is the one who all living thing must come. In the same speech Orpheus Said that: “we all are destined to you, and sooner or later will pass to your domain” (Orpheus) This statement is a clear contradiction to the Christian believes that all thing are made for the glory of one almighty God and all living thing will be judge by Jesus Christ the son of God....

Another Planet

...Your group is to present a 10- to 15-minute professional presentation in front of the class in Unit 10. If you are working individually, you are to present this by yourself. Each group member must have a speaking part, and there should be visual aids, such as PowerPoint presentations, charts, handouts, and/or videos during the presentation. Project B: Living on another Planet/Designing a Green Building Goal: Determine on which planet you want to live, or determine what type of building to design (apartment complex, business, consumer-oriented). What is needed to sustain life on another planet? You need to know the characteristics of the planet, why you would be on the planet, what you need to sustain life, and the impact of isolation on humans (assuming humans go to the planet). Similarly, if you are going to design a green/zero energy footprint building, you need to identify the purpose of the building to determine what the energy needs will be. Then identify alternative energy sources appropriate for the geographical location of the building. Both projects are of interest today. The MARS-500 project and Masdar City are examples of each. Many cities have proposed zero-energy footprint buildings in the planning stage. Living on another Planet / Designing a Green Building The Project: On 14 January 2004, President Bush proposed a new vision for space exploration that includes human and robotic exploration of the Moon and Mars.

Evidence of a New Planet

...Evidence of New Planet For years, we have known only about the 8 planets in our solar system, well 9 if you are like me and are still counting our most missed Pluto. These planets have been there for years and will be there for more years to come. However, new findings have discovered evidence of the forming of a planet approximately 335 light-years from Earth in a star. This discovery is a huge one, for that the new planet is said to grow at least three sizes the planet Jupiter. The group of astronomers that made such discovery is an international team led by Clemson University in California. These astronomers found the planet orbiting the star named HD 100546. However, what makes the scientists believe this is in fact a new planet? The reason is that, the team found carbon-monoxide emission that is the leading fact of the creation of a planet and because new studies have confirmed activity around the HD 100546 star. This new finding is a big to all astronomers for that this would allow them to test their theories in terms of the creation of solar systems, such as our very own. According to the article, since the proximity of this new forming planet is closer than other disk systems, it is easier to study in detail the process of formation. Meaning we would be able to have front role seats to such a fascinating event, at least hopefully for part of our lifetime. (Clemson University, 2014). Scientists excitedly state that once they understand what is going on in......

Planets

...The Planets and the Solar System Planets 2 " A planet is a celestial body that revolves around a central star and does not shine by its own light " (Grolier, 1992). The only planetary system that is known to man is our solar system. It is made up of nine planets which range in size and make-up. The nine major planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. There are also many other minor planets which are also in 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. Mercury which is the planet that is closest to the sun is the first planet I will discuss. Mercury is the smallest of the inner planets. It is speculated that the heat from the sun made it impossible for the gases present to become part of the planetary formation. The surface of Mercury is extremely hot. It is approximately 470 degrees celsius on the surface and is thought to be even hotter at the two " hot spots." These " hot spots " are on opposite ends of the equator. It is the heat of the surface that makes it impossible for Mercury to have any type of atmosphere. Mercury orbits the sun once every 88 days and has a true rotation period of 58.6 days. " It is the closest planet to the sun and therefore orbits faster than any other planet " (Thompson/Turk, 542, 1993). It is said that Mercury rotates three times for every two trips around the sun, so that during......

Pluto

...Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered. It is the largest and second-most-massive known dwarf planet in the Solar System and the ninth-largest and tenth-most-massive known object directly orbiting the Sun. It is the largest known trans-Neptunian object by volume but is less massive than Eris, a dwarf planet in the scattered disc. Like other Kuiper belt objects, Pluto is primarily made of ice and rock[14] and is relatively small—about one-sixth the mass of the Moon and one-third its volume. It has a moderately eccentric and inclined orbit during which it ranges from 30 to 49 astronomical units or AU (4.4–7.3 billion km) from the Sun. This means that Pluto periodically comes closer to the Sun than Neptune, but a stable orbital resonance with Neptune prevents them from colliding. In 2014, Pluto was 32.6 AU from the Sun. Light from the Sun takes about 5.5 hours to reach Pluto at its average distance (39.4 AU).[15] Pluto was discovered in 1930 by Clyde Tombaugh, and was originally considered the ninth planet from the Sun. After 1992, its status as a planet fell into question following the discovery of several objects of similar size in the Kuiper belt. In 2005, Eris, which is 27% more massive than Pluto, was discovered, which led the International Astronomical Union (IAU) to define the term "planet" formally for the first time the following......

Is Planet Earth a Religious Planet

...Is Planet Earth A Religious Planet? Kevin R. Graves Religion 212 Professor Farnham Strayer University 02/03/12 Is planet earth a religious planet? On the surface it would appear that it is. There are rituals, ceremonies and traditions that the people of earth follow in accordance with their respective religions. On the other hand, in some religions there is corruption, and misdeeds. Also, there are wars fought in the name of religion, which makes me think that religion is not a good thing. In this report, I will be reporting on five of the earth’s 20 major religions. I will be exploring their customs, practices and functions. Along the way, I will comment on the negative aspects of the religion, if any. The ultimate goal of this report is to determine if earth is a religious planet. I started my journey in the East, where I studied Christianity. In Christianity, the people attend church every Sunday or chose to worship at home in their own way. Christianity is a monotheistic religion and the people worship a higher power called God. The people of Christianity follow Ten Commandments that states: Thou shall not, steal, kill, lie, worship Idols, use the lord name in vein, commit adultery, covet what your neighbors have, and in addition to that, one should honor thy Parents, and keep the Sabbath holy. These Commandments are found in the Christian Bible, which is a collect of ancient scriptures, that the Christians hold as the Word of God. ......
