The moon :-
The moon, our nearest neighbour in space, is a natural satellite of the earth (A satellite is a relatively smaller heavenly body that revolves round a much heavier body). It has no air or water on it. It does not have any light of its own. Its observed silvery glow is only due to the light of the sun reflected by its surface. We all observe that the shape and size of the front (or bright) part of the moon appears to change gradually everyday. It takes nearly 29.5 solar days for the moon to make one complete revolution around the earth. Although one half of the moon (the half facing the sun) is always illuminated by the sun's light, the lighted up' portion, of the moon appears to change shape (as viewed from earth). This is due to changes in the relative position of the earth, the sun and the moon. During the first half of the moon's orbit, the moon's apparent size grows (waxes). During the remaining half of its orbit, the moon appears to decrease (wanes) in size. On a full moon day, the earth lies in between the moon and the sun. On this day, the full face of the moon is visible to us. On a new moon day (nearly fifteen days after the full moon day), the moon is on the 'other side' of the earth, hence, we cannot see it. On the days following the new moon day, the illuminated part of the moon (that is visible from the earth) appears crescent in shape. The size of this illuminated part goes on increasing day by day until its fuil face becomes visible again on the full moon day. These appearances or moon on diferent days, are known as the phases of the moon.

The surface of moon :-
In 1969, the American astronaut, Neil Armstrong landed on the moon for the first time; he was followed by Edwin Aldrin. They found the Moon's surface to be dusty and barren. Crates, up to hundreds of kilometres wide, cover its surface. It also has large number of mountain ranges, valleys and lava plains. The Moon does not possess any atmosphere and water; thus, there are no weather changes on it. As there is no atmosphere to trap heat, the temperature on the Moon is extreme, ranging from 100°C at 'noon' to 173°C at 'night.
