In the universe (宇宙) , as we all know, there is the Sun, the Moon, the Earth and a large number of stars. Through our Geography lessons, we know that the Sun is a star, the Earth is a planet and the Moon is a satellite (卫星) . We also 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 farther and small things also look bigger when they are nearer.
The Sun is big enough to give out strong light. The Moon can’t give out any light at all, 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 in fact the stars are much bigger and brighter than the Moon. They look smaller than the Moon also because they are farther away from the Earth.
There are many other facts about the universe and we should study hard to know more.
