Maybe many people know the universe is very big. Some scientists thought the universe seems to be rapidly expanding its component galaxies moving ever farther apart. So its very big. There are many heavenly bodies in the universe. If you stand in space, you will see many beautiful stars, like sun and other planets.
And then, lets recognize our solar system. There are eight planets in our solar system. Theyre Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The Sun is very hot. Its surface has 5600℃. Its gravitation is very strong. So the Earth goes around Sun. And the Earth is our home. Were living on the Earth, and it is the most beautiful in the solar system. It has lots of water and plants. And the moon is the Earths partner. It goes around the Earth. And other planets are very far from the Earth. So the people cant reach them and none of them has an environment with air. The people also cant live in them.
Finally, lets see in the sky in the night. There is much beautiful and magic view in the universe.
