Late discoveries of smaller objects can also be diverted in much shorter intervals. The system requires at least 200 years to design, build and implement--let's get started VOTERS ARISE

If you were an Earth hostile invader, where would you deposit a Ceres sized object to cause the most damage--off the southern tip of Africa or off the southern tip of South America on the Pacific side? The North Pole?
