  1. The Moon A look at our nearest neighbor in space!

  2. What is the Moon? 1. A natural satellite 2. One of more than 96 moons in our Solar System 3. The only moon of the planet Earth 4. Named Luna

  3. Location, location, location! 1. About 240,000 miles from Earth • 2,155 miles in diameter (about ¼ the size of Earth)

  4. The Moon’s Surface 1. No atmosphere 2. No liquid water 3. Extreme temperatures • Daytime = 265°F • Nighttime = -310 F

  5. 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

  6. Movements of the Moon: About 28 days in the cycle • Revolution – Moon orbits the Earth every 27 1/3 days • The moon rises in the east and sets in the west • The moon rises and sets 50 minutes later each day • Rotation – Moon turns on its axis every 27 days • Same side of Moon always faces Earth

  7. Far Side of the Moon • First seen by Luna 3 Russian space probe in 1959 • Surface features different from near side • More craters • Thicker crust

  8. It’s Just a Phase • Moonlight is reflected sunlight • Half the moon’s surface is always reflecting light • From Earth we see different amounts of the Moon’s lit surface • The amount seen is called a “phase”

  9. Waxing and Waning • New moon • Waxing Crescent moon • First Quarter moon • Waxing Gibbous moon • Full moon • Waning Gibbous moon • Third Quarter moon • Waning Crescent moon • New moon • Waxing- Lit side getting larger. • Waning- Lit side getting smaller.

  10. What you see in the boxes is the view of the Moon as WE SEE IT FROM EARTH!!

  12. Lunar Eclipses • Moon moves into Earth’s shadow – this shadow darkens the Moon A. Umbra B. Penumbra • About 2-3 per year • Last up to 4 hours Partial Lunar Eclipse of June 26 ; Total Lunar Eclipse of December 21

  13. Lunar Eclipse Umbra • Umbra- • Umbra-a region of the shadow where the Earth blocks all direct sunlight from reaching the Moon. • Penumbra-a region of shadow where the Earth blocks part but not all of the Sun's rays from reaching the Moon

  14. Directions: Label the lunar eclipse below. Label each of the highlighted terms below. Earth - the planet on which we live. Moon - the natural satellite of the Earth. Penumbra - the area in which the shadow of an object (in this case, the Earth on the moon) is partial. Sun - the star in our Solar System. Umbra - the area in which the shadow of an object (in this case, the Earth on the moon) is total. When the entire moon is in the Earth's umbra, we experience a total lunar eclipse. When part of the moon is in the Earth's umbra, we experience a partial lunar eclipse.

  15. Solar Eclipses • Moon moves between Earth and Sun • Moon casts a shadow on part of the Earth • Total eclipses rare – only once every 360 years from one location!

  16. Umbra- a region of the shadow where the Earth blocks all direct sunlight from reaching the Moon. Penumbra- a region of shadow where the Earth blocks part but not all of the Sun's rays from reaching the Moon

  17. The next solar eclipse that can be seen in the U.S. will be Aug 21, 2017 and will go from Oregon to South Carolina.

  18. Earth - the planet on which we live. Moon - the natural satellite of the Earth.Penumbra - the area in which the shadow of an object (the moon on the Earth) is partial, and the area in which a partial solar eclipse is experienced. Sun - the star in our Solar System. Umbra: the area in which the shadow of an object (the moon on the Earth) is total, and the area in which a total solar eclipse is experienced.

  19. The Tides • Tides caused by pull of Moon’s gravity on Earth • High tide – • Side facing Moon and side away from Moon • Every 12 hours, 25 ½ minutes • Low tide – • On sides of Earth

  20. Exploring the Moon • 1950s to 1960s - probes • Neil Armstrong First man on the Moon – July 20, 1969 • Six Apollo missions (1969-1972) 842 lbs rocks • 12 Americans have walked on the moon

  21. When will we return?

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