There is no air or water on the moon. There is no atmosphere. Cosmic dust keeps falling on it all the time.

Fill in the blanks with words given in the box.

planet; satellite; orbit; man-made; constant; face; rotate; phenomenon; heavenly

Answer:

The word ‘satellite’ comes from the Latin word ‘satellitis’ meaning attendant. The moon is Earth’s satellite. It is our planet’s constant companion in space. The moon takes exactly the same time to rotate round its axis once as the earth takes to rotate on its axis once. That is why we see the same face of the moon on earth. Scientists took an idea from this phenomenon and developed artificial satellites. Satellites are heavenly bodies that revolve round a planet. They are also called the moons of the planet. Artificial satellites are man-made objects which are put into orbit with the help of rockets.
