comment Could a planet ever end up with a doughnut hole in it?
And... the planet would be knocked off orbit, of course :D

Indeed, but we are not talking about Earth. Assuming a fast-spinning planet which does not have a spheric shape due to its axial velocity. Also, in ideal conditions, the planet would consist of lightweight materials, it would be moving in a direction opposite to the incoming body. The "projectile" would then be a heavyweight bullet-shaped axial-spinning body. Assuming the ideal conditions, I think it is possible, although the doughnut will not last for too long and the debris may end up being more then what's left :)

I understand that the forces would be huge, but what if the resulting doughnut-shaped planed would then be spinning fast enough to keep the doughnut hole empty for a while?
