Is Pluto A Planet?

315 Words2 Pages

Pluto is not a planet because it doesn’t have all the criteria needed to be defined as a planet. According to Snowbrains.com, a planet needs to orbit the sun, have enough gravitational pull itself into a spherical shape, and clear its neighborhood by being a dominant source of gravity. The text from Discoveryeducation.com states, “In 2005, space probes identified a Kuiper Belt object named Eris that is more massive than Pluto. Eris was classified as a dwarf planet within the Kuiper Belt.” In an article from Theatlantic.com, the author stated, “Upon its discovery, in 1930, scientists trumpeted that Pluto was about as large as Earth. By the 1960s textbooks were listing it as having a diameter about half that of Earth. In 1978 astronomers discovered

    Pluto should not be considered a planet. First, According to MissionScience.nasa.gov, for Pluto to be a planet it needs all three of the new criterias. It needs to orbit the sun, needs to be round, and it needs to clear its path and neighborhood around it. Since Pluto only meets two of the three expectations to be a planet, It should not be considered one. It does orbit the sun, it does have enough gravity to make it have a round shape, but it doesn’t clear its neighborhood around it.

    No, Pluto should not be considered a planet because it doesn’t have all the requirements it needs in order to be considered one. According to curious.astro.cornell.edu “In order for an object to be concidered a planet, it must do three things: orbit around the sun, have sufficient mass to assume hydrostatic equilibrium, and have a “cleared region” around it’s area.” Pluto has two of the requirements out of the three used by astronomers. Pluto does not have enough gravity to launch objects such as asteroids out of it’s atmosphere and therefore, does not follow the third rule of planets.

    Pluto Should Not be a Planet Pluto should not be a planet. According to science.howstuffworks.com, Pluto is not a planet because it doesn’t orbit the sun like the other planets. The planets in our solar system all orbit the sun in a relatively flat plane. Pluto is different. Pluto orbits the sun at a 17 degree angle to this plane.

    Pluto has been a planet since 1930. It once was in our solar system but in 2006 they decided that it wasn’t a planet anymore because it didn’t mean all the expectations. According to Discovery Education, a chihuahua is still a dog. This evidence works for Pluto because it is a very small planet but it is still a planet. Also, Jupiter is very big but it is still a planet.

    Controversy over Pluto Pluto was once considered one of the nine major planets in our solar system until 2006. The reason for this was in 2003, when an astronomer found another object in close proximity to Pluto that appeared to be larger. Based on Pluto’s size and location it was stripped of its status and was then classified as a dwarf planet. I was 11 when this event occurred. It was one of those major events in history that would result in textbooks being rewritten.

    Pluto should be a planet because in Pluto: planet or not? scientists call objects planets even though the don’t fit the criteria. And they said “In fact , about 90% of the planets known to astronomers are outside the earth’s solar system .” and “some of these extrasolar planets do not fit the IAU’s definition of a planet. Yet IAU astronomers still refer to them as planets.”

    Pluto should not be a planet, because it does not fit in the definition of “planet.” When Pluto was found it was considered a planet. Then an astronomer found something that he called Eris, this made other astronomers talked about what made a planet a "planet." This group decided that Pluto, and Eris were not really planets because of its size and location in space. Now, Pluto and objects like it are now called dwarf planets.

    Pluto should not be considered to be a planet in the Solar System. This is an accurate answer because there is so much evidence that can be provided to back it up. For example, one reason it should not be considered a planet is because it is roughly the size of other rocks in space near it, and they are closely related to Pluto in ways. It also should not be considered a planet because of its size. It is much smaller than all eight of the other planets, and around 151 Pluto’s would be able to fit inside Earth.

    Pluto should not be a planet. According to nasa.org it states, “Today, Pluto is called a “dwarf planet.” A dwarf planet orbits the sun just like other planets, but it is smaller.” At Discovery Education, it explains “The more astronomers learned about Pluto, however, the more uncomfortable they became with Pluto’s classification as a planet.” In USA Today the text states, “Another expert, Gareth Williams, associate director of the IAU Minor Planet Center, said that Pluto is not a planet, citing the official definition, which states that 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 should be a planet because it meets many of the requirements to be a planet. Pluto also has many characteristics that the other planets have. The requirements to be a planet are: -It is in orbit around the Sun. -It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape). -It has "cleared the neighborhood" around its orbit Pluto qualifies for the first two.

According to discoveryeducation.com, A group of IAU members agreed on the following criteria for a planet in the solar system. The object must orbit the sun. The object must have a spherical shape. This shape must be created and maintained by the object's own gravity source.

    Pluto is not a planet because in order to be classified as a planet an object needs to orbit a sun, have sufficient gravity to be round or slightly ovaled shape, not a satellite or moon of another object and lastly has removed debris in and around it’s orbit. Pluto is classified as a dwarf planet because it has not cleared all debris and it is unusually small. It is roughly half the width of united states and because it's so far from the sun, the temperature is around 375 to 400 degrees below zero. It orbits the sun in an unusual fashion too. It orbits in a oval shape going upwards half the time at about a 17 degree angle.

    Why is Pluto considered a dwarf planet? People consider Pluto as the dwarf planet and that it is too small to be considered an actual planet. Pluto is the 9th planet away from the sun and it still orbits the sun but it takes 248 years which is a very long time. Being the 9th planet furthest from the sun this might also be a reason for why Pluto is considered a Dwarf planet due to the length and how hard it will be to see it from earth.
