Clyde Tombaugh is not exactly a household name even though he discovered something that each and every one of us has learned about. He is accredited with the discovery of the now ex- planet Pluto. Clyde was born in Streator, Illinois February 4, 1907. At a young age his family moved to Kansas to start their own farm. Clyde had planned on going away to college the fall after moving to Kansas, but this was all put on hold when a hailstorm had ruined his families’ entire crop and he was forced to stay home and work on the farm. Clyde, while stuck on the farm, began to become interested in the sky and the stars, and at the age of 20, he started building his own unique telescopes and lenses to observe planets and he would draw what he saw. He would send these drawings of the planets to the Lowell Observatory in Flagstaff, Arizona. This eventually got him a job at the observatory due to his drawings impressing the director of the time Vesto Melvin Slipher. Clyde worked at the observatory from 1929 to 1945 and in this time he made his biggest discovery of finding Pluto in 1930.…

Pluto should not be a planet because Pluto should not be a planet because its a dwarf planet and what it takes to be a planet is to orbit around the sun, be spherical, and be the biggest thing in its orbit. Pluto is none of those. Pluto has fulfilled the first two rules to be a planet, but not the rest. Pluto is not the largest body in its orbit, but Eris (another dwarf planet.) is. Eris is 27% bigger than Pluto.…

Pluto should not be considered a planet to me because it doesn’t have a cleared orbit. Pluto should stay a dwarf planet because it is the smallest planet in the solar system. Also Pluto’s moon is bigger than it therefore, is often mistaken as a double planet. Pluto shouldn’t be a part of the planets because according to the article “Why Pluto is no longer a Planet” by Fraser Cain the…

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, Pluto will now be dubbed a dwarf planet. But it's no longer part of an exclusive club, since there are more than 40 of these dwarfs, including the large asteroid Ceres and 2003 UB313, nicknamed Xena—a distant object slightly larger than Pluto discovered by Brown last year. "We know of 44" dwarf planets so far, Brown said. "We will find hundreds. It's a very huge category." A clear majority of researchers voted for the new definition at a meeting of the International Astronomical Union (IAU) in Prague, in the Czech Republic. The IAU decides the official names of all celestial bodies. The tough decision comes after a multiyear search for a scientific definition of the word "planet." The term never had an official meaning before. What Is a Planet Today? According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit. Pluto has been demoted because it does not dominate its neighborhood. Charon, its large "moon," is only about half the size of Pluto, while all the true planets are far larger than their moons. In addition, bodies that dominate their neighborhoods, "sweep up" asteroids, comets, and other debris, clearing a path along their orbits. By contrast, Pluto's orbit is somewhat untidy. Astronomers estimate that there are at least 70,000 icy objects, with the samecomposition as Pluto, that measure…

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 further and deeper than just around the sun, they soon found out that pluto is a dwarf planet. Neptune in the past was second furthest from the sun, now the furthest as its neighbour pluto has vanished to an additional solar system.…
