  Why would I want to do that? If we were to remove any of the planets from the Solar system, we would disrupt the gravitational balance and the whole system would eventually destroy itself. Beware the laws of unintended consequences!

  I agree with john, however I would hold onto this power until a planet posed a threat on Earth such as a collision then use it when necessary.
