Neil Degrasse Tyson 's Dwarf Book

Pluto is not considered a planet because it does not meet all the criteria of a full-sized planet. The three criteria are: it has to be in orbit around the sun, it has to have a sufficient mass to assume a nearly round shape or hydrostatic equilibrium, and it has to clear the neighbourhood around its orbit. Pluto only meets two of these criteria. It has not yet cleared its neighborhood, meaning that its gravity has not cleared the space around it. In addition to this, Pluto shares its orbital neighborhood with Kuiper Belt Objects. The Kuiper Belt is a circumstellar disc in the Solar System which is beyond the planets. Therefore, Pluto is considered dwarf planet rather than a planet..

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 isn’t a planet for many reasons the main one being, it only follows two of the three criteria of being a planet. According to the article “Pluto: Planet or not?”, for Pluto to be a planet it needs to meet three pieces of criteria. In the article “Pluto: Planet or not?” it states that “Pluto meets two of these three criteria.” Therefore, Pluto should not be considered a planet because, it doesn't meet the criteria it needs to. Many scientist would agree that Pluto is considered a dwarf planet. “Pluto is a dwarf planet” Christensen wrote. It’s just plain and simple, Pluto is a dwarf planet, no doubt about it. There shouldn’t be any confusion about whether Pluto should be considered or not for many reasons. If it doesn’t meet all three

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.

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.

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

Pluto is very popular in the world and there is a lot of conversation on whether or not it should be considered a planet. Its size and unusual orbit are two factors that make it part of the dwarf family.

Today Pluto is now known as an icy gaseous white dwarf planet and is the second largest white dwarf planet with Eris being the largest. My submission will support my argument that Pluto should not be classified as a Planet or a Small Solar System Body, but a Dwarf Planet as classified in 2006, by the International Astronomical Union. First, the physical characteristics of Pluto support that Pluto has been properly reclassified as a dwarf planet. Pluto's density and size are much smaller than all other planets, as studies have confirmed that Pluto's width is 1582 miles long and the length is 1400 miles long and its mass is less than 0.024% of the planet earth.

The New Horizons space mission taught astronomers a lot about Pluto that cannot be seen with any telescope on Earth. For example, “this fascinating world has blue skies, spinning moons, …. And it snows - but the snow is red” (“Solar System Exploration: Pluto: In Depth.”). In addition to this, astronomers also discovered that Pluto had more moons than they originally thought.

I chose Pluto for this project because it seemed like an unpopular, but interesting subject. At first, I wanted to do the whole solar system, but I figured the explanations of each planet wouldn’t do them justice, because there are so many things to say about them. Also, the paper would most likely end up being fairly longer than necessary. After further thought, I figured Pluto would be the best subject for me, considering I did not know much about the so called planet that was removed from our solar system. I had a lot of research to do on the tiny dwarf.

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.

Pluto was discovered by Clyde Tombaugh in 1930. The telescope that took this picture is the most detailed view to date of the entire surface of the dwarf planet Pluto, as constructed from multiple NASA Hubble Space Telescope. Photographs taken from 2002 to 2003. (So whoever is reading this) Do you like telescopes or science? This newspaper for today will be about telescopes. Pluto is a dwarf planet. Pluto is different from most planets it’s smaller than most of them. The NASA Hubble Space Telescope from space. This telescope that took this image is a reflecting telescope.

Thesis Statement: With the advances in technology, scientist have opened the door to the discovery of Pluto,
