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 the Sun?)
It rose about 6 hours earlier It will set about 6 hours later
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
