A look at our nearest
neighbor in space!
The Moon
![Page 2: The Moon](https://reader035.fdocuments.net/reader035/viewer/2022062321/5681392e550346895da0d76c/html5/thumbnails/2.jpg)
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
![Page 3: The Moon](https://reader035.fdocuments.net/reader035/viewer/2022062321/5681392e550346895da0d76c/html5/thumbnails/3.jpg)
Location, location, location!
1. About 240,000 miles from Earth
• 2,155 miles in diameter (about ¼ the size of Earth)
![Page 4: The Moon](https://reader035.fdocuments.net/reader035/viewer/2022062321/5681392e550346895da0d76c/html5/thumbnails/4.jpg)
The Moon’s Surface
1. No atmosphere
2. No liquid water
3. Extreme temperatures– Daytime = 265°F
– Nighttime = -310

Lunar Features - Craters
1. Up to 2500 km (1,553 miles) across
2. Most formed by meteorite impact on the Moon
3. Some formed by volcanic action inside the Moon
![Page 6: The Moon](https://reader035.fdocuments.net/reader035/viewer/2022062321/5681392e550346895da0d76c/html5/thumbnails/6.jpg)
Movements of the Moon1. Revolution – Moon
orbits the Earth every 271/3 days
2. The moon rises in the east and sets in the west
3. The moon rises and sets 50 minutes later each day
4. Rotation – Moon turns on its axis every 27 days
5. Same side of Moon always faces Earth
![Page 7: The Moon](https://reader035.fdocuments.net/reader035/viewer/2022062321/5681392e550346895da0d76c/html5/thumbnails/7.jpg)
Far Side of the Moon1. First seen by Luna 3
Russian space probe in 1959
2. Surface features different from near side
1. More craters
2. Thicker crust
![Page 8: The Moon](https://reader035.fdocuments.net/reader035/viewer/2022062321/5681392e550346895da0d76c/html5/thumbnails/8.jpg)
It’s Just a Phase
1. Moonlight is reflected sunlight
2. Half the moon’s surface is always reflecting light
3. From Earth we see different amounts of the Moon’s lit surface
4. The amount seen is called a “phase”
