Earth is a general term for any planetoid object of sufficient mass to be a possibility for terraforming and Colonising. Earth is similiar to the term World and many Scientists prefere to actually call this planet Tera (Not a typing error its name was TeRa) due to its collision with another planatoid object whilst is was forming.
