The sun looks like a shiny plate, but it is really a big ball. It is always giving off light. Its flames (火焰) are very much hotter and bigger than any fire on the earth. The sun has a family. It is the biggest member in the family.

The moon is a ball, too, like the sun and the earth. Sometimes it looks as round as a plate, sometimes it looks like half a plate, or like a thin slice(片) of yellow melon(瓜).But whether you can see all of it or not, the moon is always round. Part of it is dark because it is always turned away from the sun. The moon has no light of its own. Moon light is only sunlight shining on the moon.

The moon is much smaller than the sun, even smaller than the stars. As the moon is nearer to us, it looks bigger. All day the stars are in the sky, but the light from the sun is so bright that you can not see them. Stars look as tiny(极小) as pinheads(针头), but some are even bigger than the sun. The sun looks big because it is closer than the other stars. The farther away a thing is, the smaller it looks, even if(即使) it is really very big.

The Sun's Family

　　The earth is not the only body that travels around the sun. With it are eight other planets(行星), fellow members of the sun's family.

　　Two of them are nearer while the other six are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun. People noticed long ago that these made travelling bodies move around in the sky in definite(一定的) paths.

　　We know that every little bit of matter in the universe pulls upon every other bit of matter. There exists(存在) a pull between the earth and the moon, which keeps the moon travelling in its orbit(轨道) around our planet, the earth. The gravity(重力) holds you to its surface, and pulls back to it the ball which you throw into the air. Of course the ball also pulls on the larger earth, but the earth is so much larger that the pull is not noticed.

　　Now remember that large bodies exert (施加) a greater pull on any body than smaller ones which contain(含有) less material (原料，材料). But each object in the universe, no matter how small, pulls on all other objects to some degree(某种程度).
