Pluto was considered a traditonal planet for a long as we can remeber, well at least thats how it was until 2006. In 2006 Pluto became a dawrf planet due to voting done all over the world. Even though the voting resulted in more people saying it shouldnt be a classical planet it seems more poeple are starting to think it should be. Lots of poeple would disagree with me but I think that Pluto should stay a dwarf planet.
In Kelly Dickersons’NASAS vist to Pluto has scientists debating the defention of a planet’ it is stated that there are many other objects in the Kuiper belt(where Pluto is found) that are just like Pluto as even around the same size of Pluto. If we were to consider Pluto a classical planetn wouldn't we have to consider all the objects just like it to be one as

Pluto only missed one requirement to be a classical planet and that requirement is Pluto can not clear the neighboorhood of its orbit. People on the opposing side of the agurement meantioned that if Earth were in Plutos spot Earth would not be able to meet that requiremeant either but the odds of Earth and Pluto switching are very unlikely and will never happen so why even bring it up. We dont need to worry about if they’re switched because the fact is they’re not and all we should worry about if where they are right now. Something else that stuck out to me was in’ Why Pluto is no longer a planet’ by Fraser Cain they state that the dwarf planet Eris is almost a bit bigger than Pluto. Eris is 1,600 miles across and Pluto falls a little bit behind being 1,500 miles across. This makes me think that shouldnt we consider Eris as a planet as well if it basically has the same structure as Pluto? I just dont understand why we would only have Pluto become a classical planet even there are many other objects just like it. Something that made me think about Pluto becoming a classial planet is in almost all of the given resources they all state that the defintion of
It was at first thought to be bigger than Pluto later it ended up being somewhat smaller than Pluto. Eris finishes one rotation around the Sun in 580 years. Eris is the reason why Pluto’s planetary status was changed to being a dwarf planet. The Kuiper Belt has a section called Classic Kuiper Belt. This is the busiest area of this belt and is situated at a distance of around 42 to 48 AU. In the beginning, when the solar system was created gas, dust and rocks, came together to form planets. Most of the debris was swept away by gravitational pull for those planets, but some debris survived because they were far enough away to not be affected by the gravitational pull for those planets. Finding the Kuiper Belt gave us more insight into the mystery of the objects located in the Kuiper belt. Most KBO’s are so far away that their measurements cannot be concretely calculated. By using the data collected by the Spitzer space Telescope most of the KBO’s have known sizes. In 2015 the New Horizon Spacecraft flew past Pluto for an up close exploration of the Kuiper Belt Objects. The primary real expectation of the Kuiper belt's presence, most planetary researchers now agree, originated from Uruguayan cosmologist Julio
...rst two letters of the name Pluto-was chosen as the planet’s astronomical symbol. Unfortunately, we learn later that Lowell’s Planet X theory is incorrect. In 1978, Pluto’s mass was found with the discovery of Charon, Pluto’s moon. Pluto, being a small planet, would have weak gravity. Therefore, this diminutive gravity could not affect the orbits of Uranus and Neptune. The International Astronomical Union reclassified Pluto as a dwarf planet in 2006. It was also revealed later that the strange orbits of Uranus and Neptune were due to the erroneous value of Neptune’s mass.
... Americans take for granted the technology that saves their lives in car crashes, firefighting, airplane crashes, and countless other applications. Much of the generation from the 1960’s may remember how inspired they felt by NASA’s ambition to do something as amazing as walk on the moon. Today, that inspiration is found in many smaller; yet still significant, creations for NASA programs. Somebody once dreamed of capturing an asteroid, and now NASA strives to make that dream come true. For those people who stare at the sky and question the twinkling lights blinking at them, NASA endeavors to study the more advanced systems of stars by using Pluto as a scale model. Simply because they promote better inventions, encourage creative dreams, and produce new actualities, NASA programs are worth every penny and Americans need to reconsider where they would be without NASA.
The word race is defined at its core as a competition between runners, horses, vehicles, boats, etc. to see which is the fastest in covering a set course. Well, interestingly enough, a race of a different kind occurred between two countries from the years 1957 to 1969. The competition was unclear, and the opponents were on two entirely different continents, not something as simplistic as two horses. The United States and the United Soviet States of Russia both set out as arch rivals in the “Space Race,” a quest for dominance beyond the known Planet Earth. Ironically enough, just as communism was spreading to all parts of the world, the United States always sought to squash this form of government, despite somewhat dire consequences. Now, with
Uranus is one of the Jovian planets and like the others it has a short rotation period. Uranus’s day is 17.2 hours. Its revolution around the sun however is slightly more than 84 years. It is the seventh planet from the sun at a distance of 1.78 billion miles.
science and technology. Although Pluto has many characteristics that make up a planet, it did not meet the
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 fusion (so dwarf stars are excluded) and it must be massive enough to have collapsed to a more or less spherical shape (which excludes comets, and most of the asteroids). These criteria would admit a few of the larger asteroids and probably some of the Kuiper belt objects as well, but adding a requirement for a planet to have a minimum diameter of 1,000 km would remove the larger asteroids from contention while retaining Pluto.
As technology advances on Earth, increased standards of living and life expectancy have taken a toll on Earth’s fleeting, finite resources. Kepler potentially provides scientists with information regarding planets that can serve as a future home when resources have diminished and information that can foreshadow inevitabilities about Earth through older, Earth-like planets. Kepler’s primary mission is to discover extrasolar planets within a habitable zone that have sizes relatively similar to that of Earth’s. Previous planetary research detected giant planets that were much more massive than Earth. In addition to detection, Kepler is designed to examine the planets and stars that reside in the Earth-like planet’s system.
Although Pluto was discovered in 1930, limited information on the distant planet delayed a realistic understanding of its characteristics. Today Pluto remains the only planet that has not been visited by a spacecraft, yet an increasing amount of information is unfolding about this peculiar planet. The uniqueness of Pluto's orbit, rotational relationship with its satellite, spin axis, and light variations all give the planet a certain appeal.
The history of the planet's discovery is the first we have of its kind; Uranus was the first planet to be discovered with a telescope. The circumstances surrounding the discovery of the object are befitting of the odd planet. The earliest recorded sighting of Uranus was in 1690 by John Flamsteed, but the object was catalogued as another star. On March 13, 1781 Uranus was sighted again by amateur astronomer William Herschel and thought to be a comet or nebulous star. In 1784, Jean-Dominique Cassini, director of the Paris Observatory and prominent professional astronomer, made the following comment:
Have you ever wondered how some athletes have gotten so good at a certain sport? Have you ever thought about what they did in order for them to get this good? For some the answer is simple; workout and train. But for others the answer is different; the use of performance enhancing drugs such as steroids. There are some people that argue that steroids should be legalized and allowed in professional sports. Other people argue that steroids should not be allowed. Today I am going to state my opinion and justify my reason. Steroids should not be allowed in professional sports because it can be very dangerous to the athlete’s health, it is a way to gain and un-fair advantage and it can be dangerous in both social and physical aspects.
There is so much to be discovered in our vast world of technology. Scientists and researchers work hard everyday to educate themselves and others on the advances capable of being achieved. There are people learning about new technology, different scientific and medical methods, and most of all medicine everyday. However, there is always a price to pay with hypotheses running their course through experiments, and that is the testing subject. Scientists feel the best choice for such research is to use animals to be tested, and that great achievements in the science world are worth it. Just as these scientists are, testing on innocent animals is completely wrong. Just because they are available for testing, and don’t have any ability to opt out in these experiments, does not mean they are right for the job.
“The true soldier fights not because he hates what is in front of him, but because he loves what is behind him” (G.K. Chesterton). A soldier is a soldier no matter what. If they fight behind a screen, on the front line, or from a controller as long as they’re protecting this country, the people in it, and the people fighting for it they are honorable. Some think that because one does their fighting from a remote control drone means that they have no understanding of war, and in some ways that is true, but they are still taking someone’s life when they choose to press that button just like the solders on the front line takes someone’s life when they pull the trigger. Both people are fighting the same fight: they love the country they are defending the people in it they just do it from different standpoints. Drones

In addition to its moons, Pluto has a core, geology, seasons, and an atmosphere. Alan Stern is a planetary scientist with the National Aeronautics and Space Administration(NASA). According to Stern, “I can’t think of a single distinguishing characteristic that would set apart Pluto and other things that you’d call a planet, other than its size. So I like to say, ‘a Chihuahua is still a dog.’” Also from Discovery Education the text states, “Other astronomers have noted that their colleagues sometimes call Jupiter a giant planet. Why can’t Pluto be called a dwarf planet without being downgraded from planet status?” Another fact stated from Discovery Education was, “about 90% of the planets known to astronomers are outside Earth’s solar system. Some of these extra-solar planets do not fit the IAU’s definition of a planet. Yet IAU astronomers still refer to them as planets.” USA Today stated, “The debate among Gingerich, Williams and Dimitar Sasselov, director of the Harvard Origins of Life Initiative, took place Sept. 18 with scientists, teachers and civilians watching. Two of the three, Gingerich and Sasselov, said Pluto should be a planet. A vote among audience members agreed.” Another statement mentioned by USA Today was, “Harvard science historian Owen Gingerich, who chairs the IAU planet definition committee, argued at a forum last month that "a planet is a culturally defined word that changes over time," and that Pluto is a planet.” Finally from CNN they interviewed Alan Stern, a member of NASA, who said, “We're just learning that a lot of planets are small planets, and we didn't know that before” and “Fact is, in planetary science, objects such as Pluto and the other dwarf planets in the Kuiper Belt are considered planets and called planets in everyday discourse in scientific
