Department of understanding is not enough, as we continue to observe and understand, and now give a clear definition, is normal. Clyde 'Tombaugh discovered the level of astronomical observation at the time and observing conditions, this is great. But Pluto has just been found on other planets are not the same, a small head, not enough quality. the past ten the coming year, near the orbit of Pluto found to have many small objects and it is similar to With the new findings on the astronomical observations and theoretical depth, it is the structure of the solar system have a better understanding of, and in recent years, more and more challenged by Pluto's dealt with a number of newly discovered solar system nomenclature and classification of objects makes it difficult. Zhu Jin believes that the General Assembly adopted at the IAU planet definition resolution of the solar system, planets for the original system given by a different, more specific classification of the new solar system objects, especially given the concept of the planet the exact definition is intended to bridge the traditional concept and the newly discovered planet gap. Of course, These objects include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, which are found in the 1900's. The quality of the planet also has enough,ghd piastre, round ball, but can not clear the neighborhood around its orbit of other objects, objects called Accordingly, the solar system, leaving only eight planets, Pluto is a planet because they do not comply with the new definition of planet lost eligibility, a CAS General Assembly to participate in the History of Natural Science Research Fellow Sun Xiaochun to Sun Xiaochun said that the final resolution before the adoption of the General Assembly, IAU has proposed the solar system planets from 9 to 12 of the draft, the asteroid Ceres, Pluto's satellite ~ Xena As the meeting process, a dramatic change in the draft, planetary family, not only did not Sun Xiaochun told reporters, some people used the opposition of science and culture, that the new definition of a planet over the history of science and culture, which is not consistent with the actual situation. In fact, the past is the scientific definition of planet, reflects the level of scientific understanding at the time. Now redefine the planet, in fact, both the scientific events, but also a cultural event, that science itself is a cultural phenomenon. Now scientists have to rely on scientific knowledge to the forefront is not static, Most of the world's astronomers know about planets, is a scientific conclusion, but not necessarily absolutely correct conclusion, but now it is recognized by more people.
