 When man began to search the sky,he saw a lot of things. In the universe,the earth seemed to be just a small bit of dust. It is only a small planet and travels around the sun. The sun together with its planets travels in the Milky Way (銀河）一our galaxy (星系）.The Milky Way has about thirty billion stars like our sun,and it is one of about a hundred million galaxies in the universe.

Because the space is so great,it is difficult to work out how far a star is. Instead of kilometers,we have light years. A light year means how far light travels in one year.
