Decades ago, when surveillance techniques are not as advanced technically, and scientists took as many solar system objects are defined by their lack of knowledge and experience in this period. However, the most advanced telescopes of today are the questions and a call to see all the latest research and observations. Every decade or now say that the recent performance of the instruments and telescopes, the universe opens to reveal the surprising variety of objects that have never seen or thought of people before. The most interesting is the discovery of distant planets in the Milky Way. And to make it more interesting is that there could be that our Earth. All because the planets today's researchers and stars for better understanding than before. But the stars are not as many varieties as the planets, these small worlds more complicated to understand each new observation. In our own solar system, we have a unique range of worlds in orbit around our sun, very hot water in very cold gas giants, the world of perfect beauty green and blue - the Earth. But there are many other worlds in our own solar system that are discovered and are still waiting to be discovered. Especially those who are in a region outside the orbit of Pluto, in a region called the Kuiper Belt beyond Neptune's orbit. It is a region of ice thousands of small rocky worlds that are cold and distant. These are rocky worlds called KBO Kuiper Belt objects. We know very little about them, but how in the outskirts of our solar system, both in our own backyard. Scientists and researchers are also curious to see what the KBO, and what they plan to bring us closer to finally define what exactly a planet!
It all started when astronomers from around the world met to debate on the planetary status of Pluto as a planet. In other words, deserves this little world on the edge of the solar system name of a planet where so many other places where they wander, too? Some have argued that the planet Pluto is the word revolves around its host star and its moons around him, he deserves the status. Some have said we are not quite on the outer edge of the solar system to be safe, while others argued that there may be other things like that out there, they could be called "dwarf planet" or "plutoids".In the year 2005 showed another object called Pluto, Eris neighborhood ice. After the 2006 definition of planet by astronomers: "A body that orbits the sun, without another object of the satellite is large enough in its own gravity to round most parts of bodies in orbit.” It was the last part of "clearing the neighborhood" who almost lost the battle because the discovery of Pluto in many of these icy bodies in your area. Of what they call Pluto and Eris are dwarf planets, which mean that we are only eight major planets - Mercury, Venus, Earth, Mars, Jupiter, Uranus, Saturn and Neptune.” Dwarf planet", a term, some analysts called because they thought that this little world, so far, and the elliptical orbit of a strange family of eight adults in the fall. Astronomers believe that the only reason he was called when Pluto was discovered in 1930, they knew very little space in which it was discovered the planet was but scientists have made another error in the definition compared to the other eight planets. None of the eight other planets has been "cleared the neighborhood" complete, which brings us back where we started. But then again, if all these bodies are called planets far, we could expect more and more with each new discovery to lose.
But scientists also think it's really no reason for these new worlds as a unique label as a planet, the term hard to define because of the large number of objects out there in the universe. For example, recent telescopic observations of other planets, which are not represented on a star presenter of all available resources around the sun, just move on their own in pairs, etc.We call them? In our own solar system, if we remain only on the fact that all the worlds that round due to gravity at its base and, consequently, are rounded and circle the Sun are called planets, so their number will increase thousands. What do we define need? According to a leading astronomer, when Neil degrease Tyson, director of the Hayden Planetarium in New York is one of the worlds categorization of the terrestrial planets and rocky worlds like Earth, Mercury, Mars and the gaseous giants like Jupiter, Saturn, Neptune and Uranus and Kuiper belt objects like Pluto, Eris and the asteroid as radical and others. It is interesting to note that Pluto's moon Charon and Ceres are orbits and are concentrated in Pluto as a moon, the earth, which is controlled by gravity at Earth's core.
As the researcher, Tyson said in an interview www.space.com, "planet" was the word of his measure. It is not in celebration of the scientific richness of the solar system. “The universe is vast, complex and much remains to be discovered. We have not even touched the tip of the iceberg, so to speak. So we really need definitions for a diverse group of objects associated with or should we just admire their uniqueness? We can only wait and see, to reveal what further comments on the information according beautiful cosmos.
