Explanation:
Detailed explanation-1: -Tidal forces from the moon would be eight times stronger (tides are inversely proportional to the cube of distance).
Detailed explanation-2: -The greater an object’s mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive.
Detailed explanation-3: -If the moon were suddenly twice as close to Earth, the effect would be like hitting a gong with a mallet, Comins said: Waves of energy would reverberate through the planet due to the sudden increased strength of the moon’s gravitational pull.
