Its Just a Phase Moonlight is reflectedsunlight Half the moons surface isalways reflecting light From Earth we seedifferent amounts of theMoons lit surface The amount seen is calleda phase 4. Limb The line where the surface of the moon meets the sky.TerminatorThe imaginary line between he reflected light and hadow. 5.

Orbits (revolves around)Earth every 27.3 daysElliptical orbit (not a perfect circle) About 384,000 km (240,000 miles) from Earth360,000 km 406,000 km 10224,000 miles252,000 miles 8. Moon rise times: The New Moon always rises at sunrise. The first quarter Moon rises at noon. The Full Moon rises at sunset. The last quarter Moon rises at midnight. Moonrise takes place about 50 minutes later each day than the day before. 9. Name this phase! Full MoonWhat time does this phase rise and set? 10. Is this line the limb orterminator?
