Recommended: Why pluto could be considered a planet
Pluto was discovered in 1930 by an astronomer from the United States. Pluto used to be known as the ninth planet from the sun, but today it is known as a dwarf planet. A dwarf planet still orbits the sun but is smaller than other planets. The reason we don’t classify it as a regular planet is because it cannot clear objects that are in its orbital path. This means that if there are rocks or debris it will just run into it instead of destroying it. Pluto is about 3.6 billion miles away from the sun, this is 40 times the distance of earth to the sun. Pluto is only about 1400 miles around which is half the size of the United States. The moon is slightly bigger than pluto. It takes Pluto it takes about 248 years to orbit the sun which means that …show more content…
He called this “New Planet” Eris. The finding of this new object got many astronomers thinking about if Pluto should be a planet. Soon after they declared that Pluto was no longer a planet because of it’s size and distance from the sun. These planets are now called Dwarf planets, but they are also called Plutoids which is a name given to a Dwarf Planet when it is beyond Neptune’s orbit. Pluto is very cold, this is based on the fact that it is the farthest “Planet” away from the sun making it very cold and very dark. It is 375-400 degrees fahrenheit below zero. Being that it is so far away from the earth and sun it is hard to really study Pluto’s physical characteristics but many have agreed that Pluto is covered with Ice because of the low temperature. Some of the observations that scientists have recorded are that it has a tilted orbit and it orbits in an oval instead of a circle. The main idea of Pluto is that it is a Dwarf planet that can’t clear its orbit. Pluto also is very cold and more than likely covered in ice, it also is very far from the earth and has 5 moons. Personally I do not think that Pluto should be a planet because it is too small and it can’t clear its orbital
Imagine working with radioactive materials in a secret camp, and the government not telling you that this material is harmful to your body. In the book Plutopia: Nuclear Families, Atomic Cities, and the Great Soviet and American Plutonium Disasters by Kate Brown, she takes her readers on a journey to expose what happened in the first two cities that started producing plutonium. Brown is an Associate Professor of History at University of Maryland, Baltimore County. She has won a handful of prizes, such as the American Historical Association’s George Louis Beer Prize for the Best Book in International European History, and was also a 2009 Guggenheim Fellow. Brown wrote this book by looking through hundreds of archives and interviews with people,
... 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.
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
Now that Pluto is no longer included, how many planets are there left in the Solar System?
Uranus is about 4 times the diameter of earth at 46,700km. Its mass is 15 times that of earth at 8.68*10 kg. The axial tilt of this planet is one of the most unusual things about it. It is tilted 98 degrees which classifies it as being in retrograde rotation. Uranus is also unique because it has the most inclined magnetic field. The surface magnetic field is 74 percent that of the earth. The surface gravity on Uranus is 8.87 m/s².
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.
It orbits its star once every 130 days and receives one-third the energy that Earth does from the sun, placing it near the edge of the habitable zone (NASA, 2015). Because of it’s orbiting distance from its sun, it is likely that liquid water exists on the surface, but because it is located in the outer edge of the habitable zone, it is possible that the water could freeze. However, because the planet is slightly larger than Earth, the atmosphere could be thicker, insulating the planet and stopping the surface water from becoming frozen (Kramer,
Pluto Shits on the Universe is a strong and defiant poem that expresses the rejection of rules, rules placed upon others by those who cannot even begin to control them. After being discredited as a planet for her uncharted and chaotic movements, Pluto reacts. She expresses her freedom from the rules of documented science, from our sense of time, from our titles and competition. This poem has tones of defiance, confidence and independence created through its syntax, diction, and repetition.
Pluto: A Planet of the Earth? Many issues have arisen from the debate over whether or not Pluto is a planet. Some astronomers say that Pluto should be classified as a “minor planet” due to its size, physical characteristics, and other factors. On the other hand, some astronomers defend Pluto’s planet status, citing several key features. Indeed, most of the problem is that there is no formal definition of a planet.
The moon is probably the most noticeable object outside of earth atmosphere besides the sun. There are a great number of facts about the moon. Most of these facts include size and distance of the moon compared to the Earth. Our moon's proper name is "Luna". Luna is 238,900 miles away from earth, and 27% smaller than earth. The moon is the most studied object outside of earths atmosphere. Luna is the only naturally made object that humans have set foot on besides earth.
2,870,990,000 km (19.218 AU) from the Sun, Uranus hangs on the wall of space as a mysterious blue green planet. With a mass of 8.683e25 kg and a diameter of 51,118 km at the equator, Uranus is the third largest planet in our solar system. It has been described as a planet that was slugged a few billion years ago by a large onrushing object, knocked down (never to get up), and now proceeds to roll around an 84-year orbit on its belly. As the strangest of the Jovian planets, the description is accurate. Uranus has a 17 hour and 14 minute day and takes 84 years to make its way about the sun with an axis tilted at around 90° with retrograde rotation. Stranger still is the fact that Uranus' axis is almost parallel to the ecliptic, hence the expression "on its belly".

Pluto is located 7.5 billion kilometers from Earth and is only over 2,000 km in diameter. Pluto has been labeled both a planet and a dwarf planet over the years. As said by USA Today, “a planet is a celestial body that: is in orbit around the sun, is round or nearly round, and has "cleared the neighborhood" around its orbit, meaning it is not surrounded by objects of similar size and characteristics.” Pluto only follows two of the three rules of a planet. Pluto crosses over Neptune’s orbit and is near other dwarf planets like it. Even though it breaks one rule it was officially named a dwarf planet in “August 2006”, as stated by the Library of Congress. After this event Pluto still only has one correct classification. Pluto is a planet because
Our solar system has eight planets, their moons and satellites, and they are all orbiting the Sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto used to be the ninth planet but IAU changed the definition of planet and Pluto did not meet the standards so it is now a Dwarf planet.
Even though we know a great amount more than the astronomers in the past, there is still an even larger amount we do not know about the universe to this day. Even our own solar system contains many questions yet to be answered. Some of these include the possibility of a planet beyond Pluto (Planet X), the means by which the system was created, and even the possibility of a sister star to the Sun named Nemesis. Another astronomical mystery is the creation of the universe. In time, many questions will be answered but some will always remain. Astronomy is something that will never be completely understood.
