Review Space-1

From our new home in Utah, the stars are so bright that we can even see the Milky Way Galaxy. How far is the Milky Way Galaxy from Earth?

  1. 923 light years.

  2. 92.3 light years.

  3. 9.23 light years.

  4. We are in the Milky Way Galaxy.

Think about it, and when you think you know the answer, then continue.

The Sun and you and me and all the stars that we can see are in the galaxy we call the Milky Way.
