THE WONDERS
OF THE SKY
We
look at the sky every day. But we know a little about the sky. The sky seems
blue. But if we go up very high, the sky will be dark.
The
sun rises in the east and sets in the west every day. It seems to move round
the earth, but in fact the earth goes round the sun. At the same time it is
turning round on itself. It spins round like a top. It is this spinning of the
earth that makes day and night. When our part of the earth is turned toward the
sun, it is day. When it is turned away from the sun, it is night.
The
moon is a round ball like the earth on which we live, only much smaller. The moon
goes round the earth. It has no light of its own. It takes light from the sun.
During each month the moon seems to change its shape. But it does not really
change its shape. All the time it is round ball. But we can see only that part
of it which is lit up by the sun.
The
sun is a great ball of fire. It looks so small because it is so far away – millions
of miles from the earth. It is very hot, much hotter than hottest thing we can
think of. If we fly nearer and nearer toward the sun, we shall feel hotter and
hotter and get burnt.
Our
sun is not the only sun in the sky. All the stars are suns also. Some of them
are much bigger than our sun. But they look so small because they are millions
and millions of miles away from our earth.
The stars shine in the day time as well
as at night. We can’t see them in the bright light of the sun. We can see them
only at night when the sun is not shining.
