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
it‘s 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, let‘s recognize our
solar system. There are eight planets in our solar system. They‘re 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. We‘re
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 Earth‘s partner. It goes around the Earth. And other planets
are very far from the Earth. So the people can‘t reach them and none of them has an
environment with air. The people also can‘t live in them.
Finally, let‘s see in the sky in the night. There is much beautiful and magic view in the universe.
