Moon occults (covers up) star A on the celestial sphere. In this occultation, there is a moment when star A, center of Moon, and an observer make a straight line. An artificial disk the same apparent diameter (as Moon) follows Moon at the same apparent speed (as Moon). And it occults star A in the same way (as Moon). If occultation time is the same, there will be no bending of light due to gravity.ｗ
