We see the sun, the moon and the stars in the sky. We see the sun during the day. In the day, we will see sun and clouds in the sky. The sun is a huge ball of fire. It is hot and bright. It is very far away from us. The sun is a star. It is the nearest star to the earth. It rises in the east every morning and new day beings. It sets in the west every evening. When the sun sets, it becomes dark. Then night begins. At night we will see moon and stars in the sky. The motion of earth around the sun causes formation of day and night. The sun gives us heat and light. The sun is stationary. It is a ball of burning gases.
The Moon and the stars
We see the moon and the stars in the sky at night. The moon is smaller than the sun. It is cool. The moon has no light of its own. It reflects the light of the sun. The moon keeps on changing its shape every night. When the moon looks like a ball, it is called full moon. Full moon is seen once in a month. There are millions of stars in the sky. They have their own light. The stars are different sizes. Some stars are even bigger than the sun. They look small because they are very far away from us.
We live on the earth. The earth is a planet. It is smaller than the sun. It is bigger than the moon. The earth moves round the sun in a definite path. It also moves on its axis.
