Pluto Is A Dwarf Planet

Pluto has a crust believed to be composed mostly of water ice, with a relatively thin layer of nitrogen ice mixed with small fractions of methane and carbon. However, there is no particular scientific reason why this should exclude Pluto from being classified as a planet. It is just as reasonable to claim that all planets must have rocky surfaces, like the terrestrial planets: then Jupiter, Saturn, Uranus and Neptune would have to classified as something other than “planets” (perhaps they would be minor planets?). Alternatively, it could be declared that all

Going back to the criteria the three pieces of criteria it needs to meet are, the object must orbit the sun, the object must be a sphere and it must be created and maintained by its own gravitational force, and the object must have a clear path around its orbit of other objects. Pluto does orbit the sun. It does have a spherical shape, but Pluto’s path is not clear, it is crowded with lots of other objects. That proves that Pluto is not a planet because, it only meets two of the three criteria pieces.There are rocks in outer space that are the same size as Pluto! That’s pretty small to be considered a planet. If you look at a comparison of the other planets and Pluto you will see the drastic difference. Pluto is just simply too puny to be a planet. Many people say that it should be continued to be thought of as a planet because it has been that way for a long time and that's how most people know Pluto as, a planet. That doesn’t matter though, just because people are used to it being known as a planet doesn’t mean Pluto should still be considered a planet. Facts clearly show that Pluto is a dwarf planet. There are rocks in outer space that are the same size as Pluto! That’s pretty small to be considered a planet. All in all, Pluto clearly isn’t considered a planet, because it only meets two out of the three criteria pieces to be considered a

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.

and it has to have cleared it’s orbiting path.pluto fallows the first 2 rules but not the 3rd so pluto can not be considered a planet. All of the other planets follow these rules allowing them to be a planet so pluto only qualifies as a dwarf planet.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, “all” the planets? All across the globe basically everyone says Pluto isn’t a planet. I mean sure it’s not like the others it does strange movements. But isn’t that like humanity? I mean, we don’t look the same, we are all different shapes, sizes colors, we make weird moments, does that make us not human?

The discussion about Pluto’s status in our solar system is still in question. The definition of a planet is changing as society advances and as time passes. We used to believe that Pluto was a planet which orbits the sun, but in a weird way since it’s orbit is quite odd compared to other planets in our solar system. Pluto is different such that, it has five moons and crosses Neptune’s orbit. Not only does it do that, it is quite small in contrast to the other celestial body in our solar system. As society advances, we question the definition of a planet and Pluto’s status in our solar system. Our crave for knowledge and curiosity about what’s around us motivates us to explore the unknown. Our desire to learn more is due to the fact that people

Once, Pluto was considered the ninth and most distant planet from our sun. Pluto was discovered by an American astronomer name Clyde Tombaugh in 1930. But before being discovered, an American astronomer name Percival Lowell was actually the first to caught hints of Pluto’s existence in 1905. He suggested that there was another world’s gravity that was tugging at the two planets, Neptune and Uranus, from beyond. It turns out that there was another planet, the smallest and ninth planet from the sun, Pluto. The now dwarf planet was named by an 11 year old girl from Oxford, England whose name was Venetia Katharine Douglas Phair or Venetia Burney. The astronomer did predict the planet’s location in 1915, but unfortunately he died without finding

Pluto is beautiful. Whatever its status: planet or not, New Horizons’ recent flight by the littlest “planet” confirmed that the dwarf has a lot of “heart”; and over the next 16 months, images will pour in from New Horizons to an expectant audience. Even the few pictures received thus far have caused “hoorays!” from scientists who have gathered more intel about Pluto than ever before.

Why Pluto Should be a Planet I think that pluto should be considered a planet. Was pluto not a planet once before? Why are literal balls of gas considered planets? Who gets to decide what “too small” actually means?

Pluto’s orbit is very different from the other planets in the solar system. There are three criterias you have to meet in order to be considered a planet. It has to orbit the Sun, be in the shape of a

The terrestrial planets include mercury, Venus, Earth and Mars. On the terrestrial planet, they have a rocky surface. The terrestrial atmosphere is thick and mostly made of carbon dioxide. Pluto was once known as the ninth planet originally discovered in 1930. At that time, scientists did not have all the needed tools to really study a planet so far away such as Pluto.

Pluto is the ninth planet in Earth's solar system. However, throughout the years, Pluto has had many differing views on it. Some believe that it isn't a planet at all, since it does not meet all 3 classifications of a planet (Williams Dwarf). On the other hand many scientists do still classify Pluto as a planet. Looking past all of the controversy, Pluto still has a remarkable history in astronomy.

The discussion was more of a debate since some students agreed on Pluto being a planet while others did not. It seems that humans can’t agree on things unless we have more evidence, then we will know how Pluto might be classified. Or perhaps the question of Pluto’s planet hood will be answered if given a new point of view. For instance, someone suggested that there could be different species of planets, like there are different species of plants and animals. 2)

Internal Summary/Preview: After discussing the discovery of “Planet X” through the beliefs of Percival Lowell and the actual finding done by Clyde Tombaugh, we will shift to discussing how “Planet X” got the name Pluto.

In 2006, the IAU set a definition for a planet in the solar system as the following: is in orbit around the Sun, has sufficient mass to assume a hydrostatic equilibrium (or a nearly spherical shape) and has cleared the neighborhood around the object. Dwarf Planets passed two of the three necessary requirements of the planet test. One is that they are always in orbit around the Sun and the other is that they are nearly spherical in shape. However, they did not pass the test of clearing its neighborhood of any debris. Planets are able to clear smaller bodies near its orbit such as small asteroids through collision, capture or gravitational disturbance. Dwarf planets lack the mass to do so. As a result, they have a weak gravitational force that is unable to keep its orbital influence cleared from asteroids that float around in the Kuiper Belt territory.
