Pluto Research Paper

Pluto is not considered a planet because it does not meet all the criteria of a full-sized planet. The three criteria are: it has to be in orbit around the sun, it has to have a sufficient mass to assume a nearly round shape or hydrostatic equilibrium, and it has to clear the neighbourhood around its orbit. Pluto only meets two of these criteria. It has not yet cleared its neighborhood, meaning that its gravity has not cleared the space around it. In addition to this, Pluto shares its orbital neighborhood with Kuiper Belt Objects. The Kuiper Belt is a circumstellar disc in the Solar System which is beyond the planets. Therefore, Pluto is considered dwarf planet rather than a planet..

Pluto is unlike the other planets in that it has an icy surface instead of a rocky surface, like the inner 4 (terrestrial) planets, or a deep atmosphere, like the next 4 (gas giant) planets.

Pluto, a dwarf planet, and Uranus, a planet, take turns being the most distant of the major bodies of our solar system in reference to the Sun For years, scientists were under the mistaken hypothesis that Pluto was the most distant. Scientists, in an attempt to study astronomical data, learned their hypothesis was inaccurate. Fortunately, it is of the scientists nature to investigate all data. On the basis of the data, the astronomers learned of the fact Uranus and Pluto have intersecting orbits. In addition, during the course of their investigation, they learned much of the nature of Uranus and Pluto.

Astronomers now label Pluto as a “dwarf planet” because it does not meet all of the criteria to be a planet. It is also not alone in its orbit; it is part of a wide group of small-scale objects that have been detected revolving around the Sun beyond Neptune.

Pluto was discovered in 1930 by Clyde W. Tombaugh and was reclassified as a dwarf planet in 2006. This means that for almost eighty years, all of mankind knew that Pluto was a planet. The real trouble for Pluto came in 1992 when David Jewitt and Jane Luu discovered the first celestial objects in a region now called the Kuiper Belt (Weintraub, 2015). Pluto is considered one of the largest celestial objects in the belt (Redd, 2012). However, there are some objects in

Pluto was found by a scientist in 1930. Through that time there was debates over whether this little ball of ice should be not considered a planet. It shouldn't”t be a planet because it does not dominate its neighbors.Also, Pluto’s orbit overlaps Neptune’s orbit That is not acceptable.Another Pluto has a moon a bit bigger than itself .On universe today it states “What does “cleared its neighborhood” mean? As planets form, they become the dominant gravitational body in their orbit in the Solar System…... Pluto is only 0.07 times the mass of the other objects in its orbit. The Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit.” This is saying its too small to be a planet. Also on Starchild, it says “Pluto is usually farthest from the Sun. However, its orbit "crosses" inside of Neptune's orbit for 20 years out of every 248 years. Pluto last crossed inside Neptune's orbit on February 7, 1979, and temporarily became the 8th planet from the Sun.

Known as a dwarf planet, Pluto is in the Kuiper belt, a ring of bodies beyond Neptune. It was the first discovered Kuiper belt object.

Pluto should not be considered a planet because it did not meet requirements. There are many requirements that bodies have to meet to be considered a planet. The body of pluto meets some of the requirements needed to be a planet. The requirement it meets is that's a sphere. The requirements that it doesn't hit is that it didn't clear its orbit around the

In comparison to Earth, Pluto is about 39 times further away, and therefore, it takes Pluto 248 Earth years to complete one orbit (Landau, Pluto 19). Compared to Earth’s 24 hours in a day, “a day on Pluto lasts 153 hours, or about 6 Earth days” (“Solar System Exploration: Pluto: In Depth.”). Pluto is also only 1,400 miles wide, which is “about half the width of the United States, or 2/3 the width of Earth’s moon” (“Solar System Exploration: Pluto: In Depth.”). Since Pluto is less dense than Earth, Pluto’s mass is an astonishing “one-sixth that of Earth’s moon” ( “Solar System Exploration: Pluto: In Depth.”). When New Horizons visited Pluto, it was also discovered that Pluto has a “heart shaped glacier that’s the size of Texas and Oklahoma” (“Solar System Exploration: Pluto: In Depth.”) and “mountains as high as the Rockies” (“Solar System Exploration: Pluto: In Depth.”). Overall, Pluto is much smaller and less dense than Earth, setting it apart from the other planets which are on a larger scale.

Pluto is a small planet that is very distant from the sun and extremely different from Earth. It is only 2,372 kilometers (1,474 miles) in diameter, has a retrograde (backwards/east to west) orbit, and has about one fifteenth of the gravity of Earth. So, a person who weighs 100 pounds on Earth would only weigh roughly 7 on Pluto. On Pluto, one day is about 6.39 days on Earth. Meaning within

In addition, Pluto orbits the sun in an oval shape. Most planets orbit the sun in a circular shape. Interesting addition it one year to Pluto is 248 Earth years. When Pluto orbits the Earth, it orbits the opposite way the sun orbits Earth.

First of all, you probably know Pluto fits all but one of the IAU’s, International planet requirements. The original definition of planet was a wanderer, created by the Greeks that watched these planets move for thousands of years (Scientific American). If the world had left that definition, then we would have hundreds of planets in our solar system including Pluto. In fact, we didn 't have an official definition until 2006.This meant that Pluto could no longer be considered a planet since the definition required it to have three characteristics. The IAU decided that in order to qualify as a planet, it had to orbit the Sun, be big enough for gravity to squash it into a round

Pluto has been known as the smallest planet and the 9th planet from the sun. But today pluto is known as a ¨dwarf planet”. Dwarf planets orbit the sun like all the other planets but, they are way smaller, they are also so small that they can not clear objects out of their path. Pluto has a lot of amazing characteristics, many of those include: Pluto comes from the name given by an 11 year old girl from England. Pluto's distance being 3.6 billions miles away from the sun, pluto orbits in an oval shape, pluto is found in a Kuiper

When Pluto is close to the sun in its orbit, the warmth from the sun heats up the frozen ices of nitrogen, methane and carbon monoxide on Pluto’s surface. The ices vaporize and a temporary atmosphere forms. When Pluto gets far away from the sun, the atmosphere freezes and falls back on Pluto’s surface. Pluto is too cold for liquid water. Any water on Pluto is ice. Pluto is so cold that even gases such as carbon monoxide, methane, and nitrogen exist as frozen solids. There is no liquid on Pluto’s surface, it is way too cold for that. There is a small possibility that beneath Pluto’s icy surface, there is a small liquid ocean where things are somewhat warmer.

Pluto is smaller the Earth's moons and a handful of others moons. Like the galilean moons I mentioned in a previous journal entry. Pluto has 5 moons. Charon, Styx, Nix, Kerberos, and Hydra. Charon, is the largest of the five moons, but did you know that Pluto used to be a Neptune moon, but somehow left its orbit.
