Moon Measuring

The video explains how mirrors left on the moon by Apollo astronauts are used to measure the moon's distance from Earth. Scientists fire lasers at these mirrors, and when photons hit them, the reflected light is measured to calculate the distance. This process has been ongoing for decades, providing precise data on the moon's orbit and its gradual movement away from Earth.

How accurate is the measurement of the Moon's distance from Earth?

What has been the rate at which the Moon is moving away from the Earth?
