In the universe, there is the Sun. The Moon, the Earth and so on. We know the Earth goes around the Sun, and the Moon goes around the Earth. We have day and night because the
Earth keeps turning all the time. When our part of the Earth turns to the Sun, it is day, When our part of the Earth turns away from the Sun, it is night.
Just because the Moon is closer to the Earth than the Sun, it looks much bigger than the Sun. Big things will look smaller when they are further, and small ones look bigger when they are nearer.
The Sun is big enough to give out very strong light. The Moon can't give out any light, but it looks quite bright too. Why? In fact, the light from the Moon comes from the Sun. The Moon looks much bigger and brighter than the stars. But actually (事实上) the stars are much bigger and brighter than the Moon. Also, they look smaller than the Moon because they are further away from the Earth。
There are many other planets (行星) in the universe. But of all the planets, people can only live on the Earth.
