Moon Phases and Eclipses This photo shows an “Earth Rise” taken from the Apollo 8 spacecraft as it orbited the moon.
Motions of the Moon • It takes the moon 27.3 days to rotate once. • It takes the moon 27.3 days to revolve once around Earth. Therefore, THE SAME SIDE OF THE MOON ALWAYS FACES EARTH!
Phases of the Moon • The positions of the moon, Earth, and sun cause the phases of the moon, eclipses, and tides. • The phase of the moon you see depends on how much of the sunlit side of the moon faces Earth. • Waxing = GAINING light • Waning = LOSING light

Phases of the Moon(What we see from Earth) 1. New Moon 5. Full Moon 2. Waxing Crescent 6. Waning Gibbous 3. 1st Quarter 7. 3rd Quarter 4. Waxing Gibbous 8. Waning Crescent
Solar Eclipses Warning! Don’t look directly at a solar eclipse!! • The moon comes between Earth and the sun. The moon casts a shadow on the Earth. • Only the people within the moon’s small shadow will be able to see the eclipse.
Lunar Eclipses • The Earth comes between the moon and the sun. Earth’s shadow covers the moon. • All people in the nighttime hour will see the eclipse. You can watch this one safely with your own eyes!
