Earth-Moon-Sun Earth-Sun-Moon Moon-Sun-Earth Moon-Earth-Sun
I gave my students this multiple choice question: In what order are the Sun, Moon, and Earth during a total lunar eclipse?

Only one answer is correct among these 4 choices:
- Earth-Moon-Sun
- Earth-Sun-Moon
- Moon-Sun-Earth
- Moon-Earth-Sun

Could you tell me which one is correct?

Moon-Earth-Sun
