What would happen if a big asteroid hit the moon?

You asked us, what would happen if a large asteroid hit the moon.
Thousands of meteorites have impacted the moon over the last few billion years and without an atmosphere like we have here on Earth to break up and burn these hurtling objects, the rocks have left their mark.
So what would it take to leave behind more than just a crater?
Well, an asteroid the size and mass of the moon itself would probably just destroy it or nudge it out of its current orbit around the Earth and cause drastic changes to our tides.
But honestly, all this talk is more sci-fi than hard science.
As far as we know, no asteroids even close to the size of the moon exist nearby, so it is highly unlikely that any of this would ever happen.
Which is not to say the story wouldn't make big bucks at the box office.
