Moon some facts

Moon
The moon ,the only satellite of the earth, moves from  west to east round the earth in 27 days ,7 hours and 43 minutes(sidereal month).

The same face of moon is always seen from the earth as the moon always has the same period of rotation and revolution. The moon has no light of its own. The changing position of moon in relation to the earth and the sun are known as different phases of the moon.

On full moon days the full face of moon, illuminated by sunlight, is visible from the earth when the earth lies between the sun and the moon.

On new moon days, the moon lies between the earth and the sun and therefore it seems dark from the earth.

From new moon to full moon period the moon  waxes and from full moon to new moon  period it wanes.
