I know that a object of much smaller size could cause the destruction of most, if not all, life on Earth but what size object, relative to the Earth's size and mass, would cause the complete break up of the Earth? How about the moon? Could the break up of the moon cause the break up of earth? I realize that chances are slim that this will ever happen but I was just wonder about it for the sake of knowledge.
