Do you know something about space? It is an amazing place! The solar system(太阳系) is in space.
Around the sun
The Sun is a hot, bright star. It gives off heat (热) and light. The Sun is close to the Earth. It is so large that it is almost as big as a million Earths. Most stars look tiny and you can only see them at night because they are so far away from the Earth.
There are eight planets in the solar system. We live on one of them—the Earth! Each planet moves in a way around the Sun. The Earth is called the Blue Planet because there is so much water on it and it looks blue in space.
Around the moon
The Moon is much smaller than the Earth. It may look as if it gives off light, but it doesn't. It looks bright because it reflects (反射) that light from the Sun.
