The Moon

A look at our nearest neighbor in Space!

2 What is the Moon

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

Location, location, location

About 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

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 Core

Cut to the Core

3 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 Surface

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

Lunar Features - Highlands

Mountains up to 7500 m (25,000 ft) tall Rilles (trenchlike valleys)

8 Lunar Features - Craters

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

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 Craters

Craters

Can you see the rays?

Maria

Does this photo show us a limb or terminator line?

11 Movements of the Moon

Movements of the Moon

Revolution – 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 Moon

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

13 It’s Just a Phase

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”

14 Waxing and Waning

Waxing and Waning

18 Lunar Eclipses

Lunar Eclipses

Moon moves into Earth’s shadow – this shadow darkens the Moon Umbra Penumbra About 2-3 per year Last up to 4 hours

19 Solar Eclipses

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!

20 The Tides

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 ? minutes Low tide – On sides of Earth

21 Exploring the Moon

Exploring the Moon

1950s 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
