Note on IAU classifcation.
The IAU has decided to reclassify the planets and give us a definition.
Definition:
1) Must orbit the sun.
2) Must have enough gravity to become spherical.
3) Must have cleared it's orbit from immediate debris.
Pluto, Sedna & Elis haven't done 3. So after this biased definition they are
offically removed. However I see no reason to scrap them and will
maintain their rightfull status on this site!
