The Moon is a PASSIVE defense measure - it just circles the Earth constantly, and if its gravity well just happens to suck in an asteroid, it does. It does NOT move this way and that to save the Earth, like a planetary Secret Service agent.

The moon could catch it on its opposite side—and perhaps if hit strong enough, will restore its place in its former (and nearer) orbit.
Then there's Jupiter, which has saved Earth from annihilation many times.
