An experiment to measure the instantaneous distance to the Moon

We propose an experimental technique for determining the distance to the Moon. Our technique is based on measuring the change in angular size of the lunar disk due to the variation of the observer-Moon distance, as caused by the rotation of the Earth over several hours. Using this method we obtained...

Our technique is based on measuring the change in angular size of the lunar disk due to the variation of the observer-Moon distance, as caused by the rotation of the Earth over several hours.
