Document Summary
Astronomical object that goes around the earth. Can get as hot as 260 degrees f and as cold as -170 degrees f. Moon sets in west, rises in east (like everything else) Half of the moon faces the sun, the other half faces away. We see the moon from different perspectives. As a result, we see different combinations of the bright and dark faces. Moon goes around the earth in same direction as earth rotates (counterclockwise?) From earth, only sometimes see part of illumination. Moon takes 29. 5 days to complete and orbit. Waxing crescent (normally signal of new month on lunar calendars) Full moon - will be in meridian around midnight. Gets fuller and rises later each day. Gets less full and sets later each day. From new moon to full moon - waxing. From full moon to new moon - waning. First, third quarter: moon, sun, earth at 90 degrees.
