In relation to one of my questions, Earth was destroyed after hit with a weapon that tore the planet apart by magnetic and gravitational force which does leave a large segment left floating. The rest of the mass is about in either a ring or impacted back into the remaining mass.
Now, with the distortion of and loss of pull in gravity, the pull on the moon might differ or the orbits might change. I don't quite know what the outcome would be for the moon. It's important for me to know because there's a whole mining colony stationed on the moon; I'm not expecting survivors since I expect earth-debris would rain down on the moon at one point or another.
Would the moon stay in orbit, of either earth's remains or around the sun? Or would the loss of earth cause the Moon to turn rogue and get ejected from the system/pulled into the orbit of another planet (like mars)? or would the moon's pull start to move the earth? I don't know which of these theories would be most likely to happen.
So, what would happen to the moon if earth broke apart?
