A look at our nearest neighbor in Space! The Moon Free powerpoints at
about ¼ the size of Earth
What is the Moon? A natural satellite One of more than 144+ moons in our Solar System The only moon of the planet Earth
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
Movements of the Moon Revolution – Moon orbits the Earth every 27.3 days Rotation – Moon turns on its axis every 27 days Same side of Moon always faces Earth
It’s Just a Phase Moonlight is reflected sunlight ½ the moon’s surface is always reflecting light From Earth we see different amounts of the Moon’s lit surface called a “phase”
Waxing vs. Waning What’s the difference??? Waxing –light ON from the side of the sun! Waxing – light OFF
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
Lunar Eclipses Moon moves into Earth’s shadow – this shadow darkens the Moon About 2-3 per year Last up to 4 hours
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!
The Tides Tides caused by pull of Moon’s gravity on Earth
