Prague, August 24 (AKI) - Pluto is no longer a planet. The International Astronomical Union in Prague during the Congress adopted a new definition to exclude clubs from the celestial body discovered in 1930 and lowers the number of planets in our solar system to eight.
The historic decision came after a debate that lasted several years and is not intended to exhaust itself. The new definition recognizes as planets, as distinguished from asteroids, comets and moons, all objects with sufficient mass to have become a spherical shape thanks to the shaping of their gravity and orbiting a star and not to another planet (Charon orbit around the sun and Pluto, which is superficially considered a moon, as the center of gravity with the planet is not in it but along the axis connecting the two bodies). Dozens of celestial bodies could meet the required criteria such as UB313 was discovered in 2003.
The community of astronomers, composed of 19 researchers and chaired by Owen Gingerich (but not twenty men are a bit 'too few to decide something so important ?°_°) Has therefore decided that from today will be allowed eight planets in our solar system: Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus and Neptune. The need to introduce a formal definition of planet was revealed several years ago after the discovery of a group of asteroids beyond the orbit of Pluto, smaller and less massive that the other planets in our solar system, so he applied for the position to fall under the so-called Kuiper Belt where the elements are similar.
However, since its discovery in the thirties of last century, Pluto has always been different. (eh poor pluto, not his fault ç_ç) Size and mass less than the eight others, and much more elliptical orbit. For this two years ago after a provocative exhibition at the Museum of Natural Sciences in New York, which was separated from the others, the International Astronomical Union had established a committee to clarify the nature of Pluto, through the formalization of a definition of planet. The committee has also proposed the establishment of plutonium, a subcategory of planets follow their orbits around the sun in over 200 years (ie, external to Neptune) and have highly elliptical orbits, properties considered''interesting from a scientific as they suggest sources different from those of the classical planets.''

eh anke well ... they will have their valid reasons ... But I am left to poop ° _ ° before deceive me with "caronte traghettaore-the-hell-" and then I downgraded the king of hell ... fuck. _.
