  1. Topic: The Moon

  2. The Moon The Earth’s only natural satellite A satellite is a body that revolves in a regular orbit around a planet

  3. Moon at Perigee (closest to Earth)—221,000 mi Moon at Apogee (furthest from Earth)—253,000 mi How would the Moon look when it is Closer to the Earth compared to when it is Further away?

  4. The Moon appears to change in size depending on where it’s located on its orbit. This is called ______________.

  5. Moon at Perigee (closest to Earth)—221,000 mi Moon at Apogee (furthest from Earth)—253,000 mi As the Moon gets closer to the Earth the Apparent Diameter _________ and as the Moon moves further away Apparent Diameter ___________.

  6. 2,200 mi ¼ size of the Earth

  7. No Atmosphere • --- • ---

  8. Moon’s Rotation 27.3 days!

  9. ESRT pg 15

  10. Moon’s Revolution around Earth 27.3 days!

  11. ESRT pg 15

  12. Moon’s rotation period = ___________ The same side faces the Earth We, on Earth, NEVER see the far side of the Moon from Earth

  13. Synodic period (based on Sun) = 29.53 days • (about 1 month). Fixed direction in space 29.53 days Earth Moon Earth orbits around Sun =>Direction toward Sun changes!

  14. FQ: Why does only one side of the Moon always face Earth? http://www.polleverywhere.com/multiple_choice_polls/LTc1MzE0NTgy/web

  15. Topic: Phases of the Moon

  16. Phases of the Moon caused by: _________________________________, Moon and Sun—as the Moon revolves around the Earth • Moon completes phases in 29 ½ days

  17. Phases of the Moon:Caused by the Moon’s revolution around Earth

  18. Like the Earth, half of the Moon is always lit by the Sun. • Also like the Earth, half of the moon is completely dark. • The moon does not really change, it ____________________

  19. You have to ____ the car before it _____

  20. As the Moon becomes more illuminated, it is called a ______

  21. As the Moon becomes darker, after the full Moon phase, it is called a __________

  22. New Moon • When the Moon is in between the Sun and the Earth, we cannot see the Moon. This part of the Moon is in the shade. • This is called a _______

  23. Full Moon • When the Earth is in between the Moon and the Sun, we see the whole part of the Moon which is lit up by the Sun. • This is called a _______

  24. Quarter Moon • When the Moon is above or below the Earth, we can only see half of the lit area of the Moon. • This is called a _________

  25. Crescent Moon • When the Moon is in between the new moon and the quarter moon, we are only able to see a little sliver of the illuminated side of the Moon. • This is called a __________

  26. Earth Shine ____________
