Question

You can see the full moon only once in about a month's time. Why ?

Answer 1

Answer:

There is only one full moon each month because the moon only opposes the sun once per month in its orbit. The phases of the moon are caused by how much of its visible surface is illuminated by the sun's light, and a full moon only occurs when the moon is on the opposite side of the Earth from the sun.
