The MoonA look at our nearest neighbor in Space! Free powerpoints at http://www.worldofteaching.com |

 |
What is the MoonA natural satellite One of more than 96 moons in our Solar System The only moon of the planet Earth |
3 |
 |
Location, location, locationAbout 384,000 km (240,000 miles) from Earth 3,468 km (2,155 miles) in diameter (about ? 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 |
5 |
 |
Cut to the Core3 major divisions of the Lunar interior Crust - average thickness of about 70 kilometers Mantle Core - radius is between 300 and 425 kilometers |
6 |
 |
The Moon’s SurfaceNo atmosphere No liquid water Extreme temperatures Daytime = 130?C (265°F) Nighttime = -190?C (-310 ?F) 1/6 Earth’s gravity |
7 |
 |
Lunar Features - HighlandsMountains up to 7500 m (25,000 ft) tall Rilles (trenchlike valleys) |
8 |
 |
Lunar Features - CratersUp 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 - MariaOriginally 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 |
 |
CratersCan you see the rays? Maria Does this photo show us a limb or terminator line? |
11 |
 |
Movements of the MoonRevolution – Moon orbits the Earth every 271/3 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 |
12 |
 |
Far Side of the MoonFirst seen by Luna 3 Russian space probe in 1959 Surface features different from near side More craters Very few maria Thicker crust |
13 |
 |
It’s Just a PhaseMoonlight 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” |

 |
Lunar EclipsesMoon moves into Earth’s shadow – this shadow darkens the Moon Umbra Penumbra About 2-3 per year Last up to 4 hours |
19 |
 |
Solar EclipsesMoon 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! |
20 |
 |
The TidesTides caused by pull of Moon’s gravity on Earth High tide – Side facing Moon and side away from Moon Every 12 hours, 25 ? minutes Low tide – On sides of Earth |
21 |

Exploring the Moon1950s to 1960s - probes 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 |
