Now the question arises what makes the moon so brighter and bigger in appearance?

As we all know the moon revolves around the earth in an elliptical orbit. During this revolution two points, one is apogee and the another perigee comes in picture.
So first I explain the apogee.
It is basically defined as the farthest point between the earth and the moon.
