The moon orbits us How long does this take? About 29.5 days!
How does this picture change in one day? • The Moon rises and sets. • Its appearance (phase) remains the same.
How to determine rise and set times of the moon • 1. When is the moon overhead (rather, its highest point in the sky)? • 2. What time of day is it? (Where is theSun?) • It rose about 6 hours earlier • It will set about 6 hours later
Example E W What time is it?
What about the phase? • The moon is always half lit and half dark • But it does not look like that to us • Think about what we see in the sky
Example E W What time is it?

What about outside???(facing south) East West
The Sun and moon appear to move clockwise across the sky East West

E W Example What time is it? How does the moon look?
The moon is overhead at noon It rose around 6 am It will set around 6 pm Outside East West
E W 6 hours later What time is it? How does the moon look?
It rose around 6 am The moon is overhead at noon It will set around 6 pm Outside East West
E W Example What time is it? How does the moon look?
The moon is overhead at 6 pm It rose around noon It will set around midnight Outside East West
E W Example What time is it? How does the moon look?
It will set around 6 am It rose around 6 pm The moon is overhead at midnight Outside East West
E W Example What time is it? How does the moon look?
It rose around 9 pm The moon is overhead at 3 am It will set around 9 am Outside East West
9 am 3 pm 3 am 9 pm 6 pm On this day, what time does the moon rise?
