Description: Astronomers believe that "Pluto" the track is not usually the radio rules, but eccentricity larger oval. The source of such planets, and very likely different from other planets in the solar system. With the progress of the means of observation, astronomers may have found the edge of the solar system more large celestial bodies. The future of solar system planets to expand the list if it continues, will be the new "Pluto."
