What is the distance between the earth and the moon?

Answer 1

384,403 kilometers.

This is the average distance. One of the items the Apollo astronauts left behind on the moon was a small mirror. By using a laser beam to bounce off the mirror and measuring the time it took for the beam to return to Earth, scientists were able to determine the moon's distance with accuracy because they knew the speed of light.

Method:

Z equals ct.

Whereas

Z stands for distance to an object; c for speed of light; and t for time it takes for light—whether reflected sunlight or a laser beam—to reach us.
