Document Summary

The side that is lit up isn"t always the one that"s facing us. Only during full moon do we see the entire side that"s lit up. During new moon, the entire side that"s lit up isn"t facing us. Full visible face of the moon is lit up. Look at tangents from the sun rays. Look at the different configurations of the moon for the midterm questions. I. e. when an astronaut on the moon is at a waxing crescent moon, the earth would be at a waning gibbous moon.
