      THE MILKY WAY
      The sun is one of the 200 billion stars in our galaxy, the Milky Way.
      Scientists believe we belong to a spiral style galaxy with a diameter of 100,000
      light years. Because of our solar system's position in the Orion arm of the spiral,
      we view the Milky Way as a luminous band of bright stars, without the spiral details.
