Ever since grade school you were taught that our solar system has nine planets. Sadly that is no longer the case; in 2006 astronomers have decided that Pluto no longer qualifies as a planet. Pluto is now considered a “Dwarf Planet” and has caused a lot of controversy among astronomers. A dwarf planet is not even considered to be a planet‚ and there are projected to be hundreds of them in our galaxy. Pluto is being demoted to what amounts as a third class citizen in our galaxy. Thousands of textbooks

know that our solar system has a total of eight planets‚ after they decided Pluto wasn’t a planet it was then know to be a dwarf planet. What if there are other planets in our solar system? With advanced technology they did it‚ they found another planet that’s in our solar system‚ but it’s not proven yet. The high tech computers detect a planet but it has still not been seen by the human eye. So what this means is the the planet isn’t officially a planet until it has been seen by a human for it to be

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

The Title of Planet Must be Given Back Voting done at the International Astronomical Union convention about pluto’s status of being a planet was a harsh new reality‚ with the majority voting for pluto’s demotion. Professor Alan Stern‚ chief scientist for the New Horizon mission set for learning more about pluto‚ called the outcome "an awful decision" and described the new definition as "internally inconsistent" ("Why Is Pluto No Longer a Planet?"). The debate of pluto being a planet has started

Following the discovery of the planet Neptune in 1846‚ there was considerable speculation that another planet might exist beyond its orbit. The search began in the mid-19th century and culminated at the start of the 20th with Percival Lowell’s quest for Planet X. Lowell proposed the Planet X hypothesis to explain apparent discrepancies in the orbits of the gas giants‚ particularly Uranus and Neptune‚[1] speculating that the gravity of a large unseen ninth planet could have perturbed Uranus enough

Pluto: 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. Indeed‚ most of the problem is that there is no formal definition of a planet. Furthermore‚ it is very difficult to invent one that would allow the solar system to contain all

Stewart Mrs.Ligammari Physics 11 9 June 2010 Is Pluto a Planet? When the International Astronomical Union announced that Pluto was no longer a planet people around the world were shocked. The 9 planets that they were used to knowing by the mnemonic code “My very elegant mother just served us nine pizzas” lost their pizza. Despite the fact that Pluto is a celestial object that orbits the sun‚ it cannot be considered a planet because of its inconsistency in orbit‚ its size‚ and the abundance

Pluto Not a Planet‚ Astronomers Rule Pluto has been voted off the island. The distant‚ ice-covered world is no longer a true planet‚ according to a new definition of the term voted on by scientists today "Whoa! Pluto’s dead‚" said astronomer Mike Brown‚ of the California Institute of Technology in Pasadena‚ as he watched a Webcast of the vote. "There are finally‚ officially‚ eight planets in the solar system." In a move that’s already generating controversy and will force textbooks to be rewritten

Once known as the ninth planet of the solar system‚ Pluto is now the second-largest dwarf planet. Composed primarily of ice and rock‚ Pluto took part of our Solar System for 76 years. It was discovered on January 23‚ 1930 by Clyde Tombaugh. Tombaugh was an American astronomer who worked at the Lowell Obeservatory. Tombaugh had been working on a project when he came across a moving object in photographs he had taken of the celestial sky. After observing a lower quality picture taken of the mysterious
