If Apophis going to fly by Earth within 20,000 miles in eight years maybe we should strike it with a missile carrying a hydrogen bomb to knock it out of an Intersecting orbit forever. with something this close we definitely have the technology to take it out and would make a nice light show at night.
Any nuclear explosion would have to be planned to occur far enough away from earth to ensure that Earth would not get too strong of an electromagnetic pulse (EMP) that would know out electrical grids.
