1. A look at our nearest neighbor in Space! The Moon Free powerpoints at http://www.worldofteaching.comhttp://www.worldofteaching.com

2. What is the Moon? A natural satellite One of more than 96 moons in our Solar System The only moon of the planet Earth

3. Location, location, location! About 384,000 km (240,000 miles) from Earth 3,468 km (2,155 miles) in diameter (about ¼ the size of Earth)

4. Birth of the Moon “Born” 4-5 billion years ago Formed from impact of Mars-sized “planetesimal” on Earth Debris from both objects melted together to form the Moon (collision theory)

5. Cut to the Core Diameter is only ¼ Earth’s diameter Average density is about the same as the density of the Earth’s OUTER LAYERS

6. The Moon’s Surface No atmosphere No liquid water Extreme temperatures –Daytime = 130  C (265°F) –Nighttime = -190  C (-310  F) 1/6 Earth’s gravity

7. Lunar Features - Highlands Mountains up to 7500 m (25,000 ft) tall Rilles (trenchlike valleys)

8. Lunar Features - Craters Up to 2500 km (1,553 miles) across Most formed by meteorite impact on the Moon Some formed by volcanic action inside the Moon

9. Lunar Features - Maria Originally thought to be “seas” by early astronomers Darkest parts of lunar landscape Filled by lava after crash of huge meteorites on lunar surface 3-4 billion years ago Mostly basalt rock

10. Maria Craters

11. Far Side of the Moon First seen by Luna 3 Russian space probe in 1959 Surface features different from near side –More craters –Very few maria –Thicker crust

12. Exploring the Moon President John F. Kennedy launched space programs to encourage the exploration Neil Armstrong First man on the Moon – July 20, 1969 Six Apollo missions (1969-1972) –382 kg (842 lbs) rocks 12 Americans have walked on the moon

15. When will we return?

16. Ice on the Moon? 1994 – Clementine probe 1998 – Lunar Prospector

17. Moon base of the future? What would you need to live there?

23. Does this image show us the near side or far side of the moon? Far Side How can you tell?

24. Name this phase! First Quarter

25. Name this phase! Waxing Crescent

26. Does this image show the near side or the far side of the moon? Near Side

31. What might be happening in this image? Lunar Eclipse

32. Name this phase! Look closely! Waxing Gibbous

33. True or False: The Far Side and the Dark Side of the moon are the same thing. False!

34. Name this phase! Full Moon

35. Name this phase! New Moon

36. Does the moon rise or set in the west? It sets in the west.

37. Name this phase! Waning Gibbous

38. Name this phase! Waning Crescent

39. Name this phase! Waning Gibbous
