Here is your short paragraph on Moon !
The only natural satellite of Earth is the Moon. Just as the Earth rotates around the sun, the Moon rotates around the Earth on its own axis.
The Moon is one among the smallest heavenly bodies, which could be seen from Earth.
The moon does not have a light of its own, but shines from the reflection of the light from the Sun. Since the moon takes almost 29 ½ days to complete one rotation on her axis, it would almost appear the same for us on Earth as we see only the same side for most of the time.
When taken a closer look, it is understood that the surface of the moon is hard and cold, just traces of either ice and snow or rock and sand. Life cannot exist on moon and hence no kind of vegetation or animals are found.
The moon is a mass of big mountains and extinct volcanoes. Several craters are found on moon. This is what we see when we look at the moon with our naked eye, though the crater are not distinct from earth, the irregularities are seen miles apart.
The moon does play an important role in the formations of calendars. Apart from it, the lunar eclipses also form where the sun, moon and earth comes in a row and the moon falls in the shadow of the earth. Soon after the eclipse, when the earth moves away, one would find a small crescent moon which then rotates forming the full moon and half moon on its journey.
Neil Armstrong was the first person to land on Moon and makes a detailed study on the moon. Ever since then, man has travelled to moon often and researches are going on to find if life could exist on moon at some point of time.
