根据最新的测量结果，在2003年所发现的UB313竟然直径比冥王星更大，因此再次点燃起了UB313是否可被称为一个行星，甚至被称为我们太阳系的第十行星的问题。
德国波昂的Max Planck Institute无线电波天文学研究所的Frank Bertoldi利用位于西班牙的Institute for Millimetre Radio Astronomy所拥有的直径三十公尺的望远镜来观测来自UB313的无线电波。用这个方法可以了解有多少来自太阳的热量被UB313所吸收并以辐射的方式放出。用这个方法可以推测UB313的大小及表面温度。

A planet larger than Pluto has been discovered in the outlying regions of the solar system.
The planet was discovered using the Samuel Oschin Telescope at Palomar Observatory near San Diego, Calif. The discovery was announced today by planetary scientist Dr. Mike Brown of the California Institute of Technology in Pasadena, Calif., whose research is partly funded by NASA.
