Informative Speech: The History of Pluto Essay

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

Unless the criteria for planets changed Pluto shouldn’t be flipflopping back and forth. This shows that emotions for certain objects, such as Pluto, aren’t exempt from those that make the debatable decisions. Why do peoples’ emotions get in the way of making decisions? Decisions should be based off of facts, not how one feels during one specific time. Looking off of the facts also helps there from being any bias.

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.

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

According to Columbia Electronic Encyclopedia in "Lowell Observatory" it that the Lowell Observatory located in Flagstaff, Arizona. “… it was founded in 1894 by Percival Lowell, the American astronomer who popularized the idea that Mars might support intelligent life.” The original telescope is still working and it is “located at the Mars Hill …” When “Clyde Tombaugh” discovered Pluto he was using Lawrence Lowell photographic camera. Also, in the Lowell Observatory there is a night viewing program for the visitors'.

Percival Lowell came to Flagstaff in 1894, Arizona was still a territory, and Flagstaff had a population of less than 1,000 people (Putnam). In 1930, Flagstaff was put on the map with the discovery of Pluto, using Lowell’s calculations, and became the first planet discovered outside of Europe. People flocked to the up and coming science-based town, revitalizing the population to 8,000 by 1955. As the population boom was upon this quiet wooded town, the U.S. Naval Observatory Flagstaff Station was established, as was the U.S Geological Survey in 1963. With more observatories being built and the advancement of the natural sciences, the need for the preservation of dark skies in Flagstaff became apparent (Flagstaff’s).

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,

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.

It was discovered in Arizona, USA and an eleven year old girl from England won the naming contest, naming the new planet "Pluto" after the Roman god of the underworld. Astronomers are not certain, but they think that the composition is similar to Triton's with 70% rock and 30% ice. It has a low pressure atmosphere containing nitrogen, methane, and carbon dioxide. It is about one sixth the mass of Earth's moon and has five natural satellites, it's most famous moon being Charon. The other four moons were discovered in the 21st century, named Nix, Hydra, Kerberos, and Styx. There is a spacecraft called New Horizons that has just made it to Pluto. This fairly recent discovery, however, did not even make a full revolution around the sun before it was demoted to a dwarf planet for not complying with the last of the three planet requirements: "It has cleared the neighborhood of its orbit of any other space debris." It has now been named a dwarf planet, a title given to celestial bodies what are missing just one of the three requirements to become a

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.

Tombaugh at the Lowell Observatory in Flagstaff, Arizona. After a year of observations and research =, Tombaugh finally discovered an object in the right orbit, and that's when him and his team discovered Planet X. Since the Lowell team discovered “Planet X” they were able to name the planet. They decided to name it Pluto, a name suggested by an 11 year old schoolgirl in Oxford, England. It was names after the Roman God of the Underworld.
