  1. The Moon Content Credit To: After School Astronomy Clubs Dorian Janney Tanglewood Nature Center Jonathan Hodge

  2. “It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.” Neil Armstrong

  3. What do you think? • How far away is the moon? • The moon is at an average distance of 238,855 miles • (Did you know there’s an app for that?!!) • How big is it? • The Moon is approximately 27% the size of the Earth • You would need 81 objects with the mass of the Moon to match the mass of the Earth! • The surface area of the Moon is 37.9 million square kilometers • The continent of Asia is 44.4 million square km

  4. How long did it take astronauts to travel there? • It took three days to get to the Moon • How long would it take you to drive there? • Travelling at 65mph, it would take about 153 days, 2 hours and 34 minutes to drive to the Moon (without traffic!!) What do you think?

  5. Astronauts on the Moon • From 1969 through 1972, six pairs of astronauts landed on the Moon

  6. Fun Fact! • The Apollo 11 spacecraft was equipped for its mission to the Moon with a state-of-the-art on-board computer. The CPU ran at a pace of 1 Megahertz, and the system memory was 36K in size. • Currently, the typical home computer is equipped with a CPU running at least 800 MHz and many hand-held calculators contain more than 36K memory.

  7. Why could this footprint be on the Moon for about 10 million years?

  8. How does the Moon move? • The Moon orbits the Earth, and rotates on its axis and is kept in it’s orbit by the Earth’s gravity • How long does it take the Moon to orbit around the Earth? • The Moon orbits the Earth in a little under 28 Earth days. It travels at almost 2,290 miles per hour The Moon’s Movement

  9. How long does it take the Moon to rotate one time? • The Moon's rotation period is also a little under 28 days • the same face points toward the earth during its entire orbit The Moon’s Movement

  10. The Moon’s Surface • What do you see on the Moon’s surface? • Mountains and Valleys? Which is which?

  11. The Moon’s Surface • How do the surface of the Earth and the Moon compare? • Why aren’t there any oceans on the moon?

  12. Waxing and Waning

  13. How was the Moon formed? • The moon was probably once a piece of the Earth that came off when an asteroid (as big as Mars!) hit the Earth about 3.5 to 4.5 billion years ago.

  14. Lunar Reconnaissance
