So does this mean the Earth has not yet cleaned its orbit? And thus needs to be classified as a dwarf planet?

Our orbit is quite dirty there are probably over 10,000 NEO's, but Pluto's orbit is even dirtier. Earth is the 30 year old single guy/gal, Pluto is the 19 year old college slob.

I think the criteria is that it has cleared its orbit of similar sized bodies. Smaller bodies are OK. Pluto has several bodies of similar size in its neighborhood.
