The word planet is derived from the ancient Greek word planetes‚ or “wanderers.” Though the visible planets of that time did appear to be wandering in the sky‚ the science of Astronomy has broadened this term as well as our understanding of what‚ in fact a planet is. By modern definition‚ “planet” is described as a celestial body other than a star‚ which orbits a star. Our Solar System orbits the center of our home galaxy‚ the Milky Way‚ and has a rich and varied structure. It consists of the

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

Pluto: 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

Kwame 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

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

Well‚ a planet is described as a celestial body that is in an orbit of the Sun‚ has a near round shape‚ and doesn’t enter an asteroid field. Simple answer‚ right? No‚ Mostly because when Pluto was a planet‚ it had most of all of those features‚ only that it didn’t orbit the sun like the closer planets. Pluto was considered a dwarf planet after only fulfilling 2 requirement‚ no Planeteering for this guy. Alright then‚ what is the definition of a planet? In the dictionary‚ a planet is defined

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

here to talk about the little planet named Pluto. I personally think it’s unfair to the planet to be named something and then drawn back‚ Then again they had hard evidence on to why they did it. So I am going to give you the top reasons on why they took its righteous calling of a planet back. One of the main problems is its size. Many people thought it was too small to be called a planet and referred to it as the star. Ryan C. of the planetary society said: “ Pluto is a Disney character who has been

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

To be considered a planet of our solar system you need many different aspects which may seem effortless to understand although there is endless information which is new to scientists everyday. Pluto has some but certainly not all the qualities as it was found orbiting the Kuiper belt which is beyond the orbit of Neptune‚ the current furthest planet from the sun. Pluto has been one of the 9 planets in the past‚ but now that scientists have higher tech machines and programmes to allow them to explore
