Why doesn’t the moon eventually collide with Earth or drift away?
It is very slowly drifting away at like 4mm per year or something. We can measure this with lasers and what is essentially a mirror that was placed on the surface. Edit sorry > "The Moon continues to spin away from the Earth, at the rate of 3.78cm (1.48in) per year, at about the same speed at…
