Earth in the solar system

How nice to look at the sky after sunset. At first one or two shining dots are visible in the sky, but later their number increases. You can't count them. The entire sky is full of tiny luminous objects, some of which are bright and some are faint. It seems as if there are diamonds in the sky. Some of these seemed to twinkle. But if you look at them carefully, you will find that some of them have a different flicker than others.



Along with these bright objects, you alsoals see the moon almost daily. It at different times in different sizes and in different positions.

You can see the full moon about once a month. halfIt is a full moon night or a full moon. You can't see it after fifteen days. This is the new moon night or new moon. If the sky is clear on such a night, then you can observe the sky well.

Don't you wonder why we can't see the moon and all these small bright objects during the day? This is because, due to the very strong light of the Sun, we are not able to see the objects that shine during the night.

Sun, Moon and all those objects which shine in the sky during the are called celestial bodies.

Some celestial bodies are large and hot. They are made of gases. They have their own heat and light, which they emit in large quantities. These celestial bodies are called stars. Sun is also a star.
