Pluto Moons
Pluto is a dwarf planet orbiting the Sun, with about a sixth of the mass of the Moon and a third of its volume. Like other Kuiper belt objects, which are generally outside Neptune's orbit, Pluto is primarily rock and ice. It has an elongated and highly inclined orbit that takes it from 49 astronomical units (7.4 billion km) away from the Sun down to 30, closer than Neptune. Light from the Sun takes about 5.5 hours to reach it at its average distance. Since its discovery in 1930, it had been considered the ninth planet, but the International Astronomical Union came up with a new definition for planets in 2006 that excluded Pluto after many other similar icy objects were found, including Chiron and Eris. Pluto has five known moons: Charon (about

    Should Pluto Be Considered A Planet

    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…

    Pluto No Longer a Planet

    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.…

    Plutonium and New York

    An American Chemist named Glenn T. Seaborg discovered plutonium in 1941 at Berkeley University in California. The discovery of Plutonium was not announced until 1946 because America was at war with Japan and Germany. Plutonium was named after the planet Pluto, after the planet Neptune in the solar system and Neptune gave its name to Neptunium. <br><br>Plutonium is a silvery metal that turns yellow when exposed to air. It is warm to the touch due to the releasing radioactive energy from it. The atomic number of Plutonium is 94. It has an average atomic mass of 244. The symbol for plutonium is Pu. Plutonium is a lot like calcium. This is why take its place in bones, breaking down marrow cells and in doing so causing leukemia.<br><br>Plutonium appears very little in nature. It can be produced by bombarding uranium with the nucleus from a hydrogen ion. This hydrogen ion is called deuterium and so the nucleuses are called deuterons. There are 15 known isotopes of plutonium. They range from an atomic mass of 232 to 246. Plutionum-239 is thought to be the most important. It can be split into two parts called "fission fragments" that release large amounts of energy. It melts at 641 degrees Celsius and boils at about 3232 degrees Celsius. <br><br>Plutonium is made in large amounts by nuclear reactors. Since it 's easy to produce it is used a lot in nuclear weapons. An amount of Plutonium about the size of an orange is enough to fuel a nuclear reactor. It is also used as a battery in heart pacemakers. Furthermore, it has been used to power some forms of spacecraft.<br> <br><b>Bibliography</b><br><li>Encyclopedia of science and technology, 7th edition. McGraw Hill, New York.

    The Planet Neptune

    Neptune, the eighth and last planet in the solar system, it is so-called after the Roman god of the sea. This magnificent blue gargantuan is quite similar to Uranus in scope and composition, but much further than the Sun, it takes Neptune about 164 years to orbit the Sun. Like other gaseous planets Neptune turns at a tremendous speed on its axis, making one day about 16 hours long. A visual of Neptune cannot be perceived with the naked eye; however, one can view a pinpoint of the planet through the usage of a pair of binoculars. (www.solarview.com).…
