Is Pluto a Planet?
Many people say that Pluto is not a planet, while some others state that it is. Pluto is a planet, as it contains many of the characteristics.
According to Discovery Education, Pluto has two of the three characteristics of being a planet. But, Discovery Education also said that the so-called “must-haves” to be a planet, were not established before 2006. Alan Stern, a planetary scientist stated the analogy that a chihuahua is still considered a dog, so Pluto should still be considered a planet no matter the size. According to Space.com, Stern also replied to the many people who were saying that Pluto is not a planet because of its “neighbors” by saying that “A river is a river, independent of whether there are other rivers …show more content…

In fact, there were no set rules for what made a planet a planet until the IAU stated them in 2006. Therefore, this means that there are no exact things that define a planet, and that some should be established by many different groups, not just one. Stern’s analogies show that there are many other things that are still considered one of their species or “kind” no matter the size or “neighbors”. This shows that things should be based on its qualities and characteristics rather than size. Pluto does indeed have moons, which is the same as many of the other celestial bodies that are indeed considered a planet. Also, the IAU’s definition is not necessarily true to all of the planets in our solar system. This shows us that the criteria cannot be met for all of the other bodies stated as a planet so therefore, the rules either have to be changed, or else, Earth is also not considered a planet. Finally, some say that Pluto is also too far out to be a planet, but, from 1979 and 1999, Pluto was closer to the Sun than Neptune. This shows that if Pluto was considered too far away to be a planet, then Neptune could not be considered a planet as it would be too far away from the

At the beginning both characters were very suspicious of each other. Their perspective on everything was a perspective with a lack of knowledge which caused a lot of suspicion and mystery. However as the story progressess Pluto and Thomas get to know each other and gain the knowledge to make the right conclusions about each other. I feel like the only reason that Thomas and Pluto could not make much progress through their relationship is because of the treasure. Pluto was extra protective from the Smalls since they were new and he did not know enough to trust them.

Article one of Pluto from science daily on the New Horizons map of Pluto: The whale and the donut. Shows the overview of the latest map of the on and off again named plant at the end of our solar system. The latest map of Pluto was providing by Ritchey-Chrétien telescope from the company named New Horizon being part of NASA, its primary mission to perform a flyby study of the Pluto system. On a mission that change the question to many explorers wanted answers to, how does Pluto look like? Well, their question was answers on July 9, 2015 that gave a close-up of Pluto.

Pluto, should once again be considered as a planet once again. First of all, Pluto fits two of the three requirements to be considered a planet. The currently considered dwarf planet has what Earth and most planets have such as moons,rocks,and ice and isn’t that small. The blue dot is also largely undiscovered celestial body and there is a long journey ahead. Another reason is that the head of NASA said that he considered Pluto, the blue dot as a planet.

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.

Out of the eight planets in our solar system, Uranus is the seventh farthest away from the sun and cannot be seen by the naked eye. It was actually the first planet to be discovered with the use of a telescope. The discovery of Uranus was made on March 13th, 1781 by William Herschel, a british astronomer and composer who was born in Germany. Uranus is described to be “rolling around on the sun on its side” because of the fact that is was tipped on its side with a tilt of ninety-eight degrees. Herschel originally thought that he discovered a comet but after a few years it was classified as a planet.

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.

No Pluto is not a Planet it is a Dwarf Planet because it does not meet the criteria to be a planet. 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.

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 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.

Pluto is a planet, because it consists of all of the qualities that the other planets have. According to usatoday.com, “Harvard science historian Owen Gingerich, who chairs the IAU planet definition committee argued that a planet is a culturally defined word that changes over time, and that pluto is a planet.” In an article from missionscience.nasa.gov it states that “According for something to be considered a planet, it must consist of three things. First it must orbit the Sun, second it must be big enough for gravity to form it into a ball, and third it must have cleared other objects out of the way in its orbital neighborhood.” Pluto consists of the first two qualities, but the third one is the quality that causes debate.”

A lot of people say that Pluto is a planet, but many also say it is not. People also considered Pluto a dwarf planet because it is small in size and so far from the other planets. There is three criterias that all planets including Pluto have to meet to qualify to be a planet and Pluto only meets two out of the three criterias. Pluto orbits the Sun and has its own spherical shape created and maintained by its own gravitational force just like all of the other planets. There is just one criteria that Pluto doesn't meet that all the other plants do meet.

Mercury is the closest planet to the sun, which makes it the most difficult planet for scientists to study. If you could stand on mercury, the sun would look three times bigger than on earth. Mercury can get as close as 47 kilometers to the sun. A big difference between Mercury and all the other planets is the size of its iron core. Mercury’s iron core makes up about 65 percent of its total mass.
