Kuiper Belt and Pluto
The Pluto/Neptune anomaly of the Titius-Bode progression is predicted in the Initial Mass Displacements of the Solar System. [1]
Although the total Ceres includes an asteroid belt (2.8 AU), the total Pluto mass is unique. Excluding Neptune, a variety of objects (Kuiper Belt) between 48.8 AU and 28.8 AU had a total mass of 10 Earth masses (i.e., Pluto Initial Mass).--FrankHatch 18:30, 12 September 2009 (EDT)
