Astronomer Clyde W. Tombaugh's Discovery Of Pluto

Many issues have arisen from the debate 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.

Pluto was discovered by Clyde Tombaugh from the Lowell Observatory in Flagstaff, Arizona in 1930.

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

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.

Neil DeGrasse Tyson wrote The Pluto Files: The Rise and Fall of America’s Favorite Planet to examine why Pluto ought not to be considered a planetary body and instead a dwarf planet or Kuiper Belt Object.

Pluto being a planet is a controversial topic all over the world, should Pluto be a planet? Or should we exclude Pluto from being a part of our solar system. Here are three agreements that could be made to support the fact that Pluto should never become a part of our solar system. There are three characteristics that an object in space must have to be classified a planet and there are three characteristics as well to be classified as a dwarf planet, a dwarf planet must be able to orbit the sun, just like all objects in our solar system; a dwarf planet has to be small enough for the mass to not be able to clear its neighborhood; also, the entail shape needs to be round. Now the criteria for a planet is roughly the same as a dwarf planet with the exception of one characteristic.

In the Solar System there is nine planets total counting Pluto and eight not counting pluto. Named after the Greek god of the underworld Pluto is the ninth of the nine planets from the sun. Pluto was discovered in February 18, 1930 by Clyde Tombaugh. Plutos the only orbit planet in the Solar System after it was classified as an orbit planet back in 2006. The planet has nine moons total Charon, Hydra, Nix, Kerberos, and Styx. Although Pluto is the largest Dwarf Planet it's smaller than most moon of the other planets. Alongside Pluto is the eighth planet from the sun otherwise known as Neptune. Due to its blue coloration Neptune was named after the Roman god of the Sea. While neptunes the third largest planet with respect to mass, according to diameter it's the fourth largest. Neptune has 14 moons and a very thin collection of rings that are made up of ice and dust

My Thesis statement is Phuto was once considered to be a planet but now Pluto is the most famous dwarf planet in our solar system. Pluto is made up of ⅔ of rock and ⅓ of ice. Pluto was discovered by Clyde Tombaugh on January 23, 1930. Pluto is very very cold you can't even imagine how much colder it is than Antarctic.If that happen in Earth the air would turn into snow that's how cold it would be about 230 degrees below zero Celsius. When you want to see Pluto up in the sky you can't even see Pluto with your naked eye. Pluto is very hard to see once you look in the telescope it look a little like a star even with the telescope.

In the outer limits of our solar system there is a planet unlike any other, Pluto. Pluto was discovered in February of 1930 by an American astronomer, Clyde Tombaugh. It is the only planet to have been discovered by an American. All though we have known of the existence of Pluto for over thirty years now, there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto, Adding to the obscurity of this strange planet is that the capability to send spacecraft such distances has never been achieved. Through the wonders of science and astronomy, there are many things that can be determined, concluded, and hypothesized about this obscure planet.

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

Clyde Tombaugh, during his discovery of the planet Pluto, was a farm boy and an ameteur astronomer employed by Arizona’s Lowell Observatory in search of the mysterious Planet X. During his search, the roaring twenties was in full swing and during this time,

The present unknow ninth planet was discovered in 1930, pluto is the second smallest planet from the solar system and most massive dwarf planet. Pluto down to the newly created classification of ¨dwarf planet.¨ There are still many objects with similar size and mass to pluto jostling around its orbit. The dwarf planet Pluto is named for the ancient Roman god of the underworld. In Roman mythology, Pluto was the son of Saturn who, with his three brothers, controlled the world: Jupiter controlled the sky, Neptune controlled the sea, and Pluto ruled the underworld.

Today we are going to talk about Pluto and its features. Pluto is a dwarf planet, it is very cold and its orbit takes longer to revolve around the sun than other planets. Pluto is not considered a planet now but it was before a meteorite knocked it out of orbit a long time ago. Pluto is much further from the sun than the other planets. Because it is so far out it takes longer to orbit the sun.

b. Jennifer Rosenberg in her article Pluto Discovered writes, “It took a year of detailed, painstaking work, but Tombaugh did find Planet X. The discovery occurred on February 18, 1930 while Tombaugh was carefully examining a set of photographic plates created by the telescope”. Tombaugh officially announced the discovery of the ninth planet on March 13, 1930.
