Synopsis

There are many features of the Earth and its moon that make the earth ideally suited for life and humanity. Thus the earth is unique in our solar system. But what about the more than one thousand planets orbiting other stars that astronomers have discovered in recent years? None of these planets are suitable for life. As we learn more about astronomy, the uniqueness of Earth becomes even more clear!
