由此看来，即使国际天文学联合会保住冥王星的行星地位，经典的太阳系九大行星理论也仍然要改，只是改法相反而已。
It seems that even if the IAU had kept Pluto's status as a planet, the classical theory of nine planets in the solar system would have had to be changed, but the other way around.
根据国际天文学联合会的定义，“矮行星”应该有一条环绕太阳的轨道，它不能清除其轨道附近的其它天体，而且不是一颗卫星。
According to IAU, a "dwarf planet" should have an orbit around the Sun. It will not have a clear neighborhood around its orbit, and must not be a satellite.
