Nevertheless, there is enough dispersion of the beam that it is about 7 kilometers in diameter when it reaches the Moon and 20 kilometers in diameter when it returns to Earth. Because of this very weak signal, observations are made for several hours at a time. By averaging the signal for this period, the distance to the Moon can be measured to an accuracy of about 3 centimeters (the average distance from the Earth to the Moon is about 385,000 kilometers) This experiment, like every astronomical experiment assiumes that light speed is constant. It is not. True, the moon's orbit is pretty circular (e = 0.054) but that is enough to make quite a difference to the speed of the return pulse.
