Spend some time with it! 5. Explain the phases of the moon and eclipses. 6. How did the motions of the planets shape the history of astronomy? 7. What are Kepler’s Laws?

A list of important terms: 1. apparent retrograde motion - The apparent motion of a planet, as viewed from Earth, during the period of a few weeks or months when it moves westward relative to the stars in our sky. 2. astronomical unit (AU) - The average distance (semimajor axis) of Earth from the Sun, which is about 150 million km. 3. astronomy - the branch of science that deals with celestial objects, space, and the physical universe as a whole. 4.
