We can see the moon during the full moon when it is behind the earth because of the way it orbits around the earth.
Explanation:
- The moon orbit around the earth at a tilted angle to the orbit of the Earth around the sun.
- Furthermore, during the full moon, the moon will exhibit either behind or at the top of the earth's shadow.
- Because of the tilted orbit, when it is behind the earth's surface it is away from the earth's shadow with the exception during the Lunar eclipse.
- During the Lunar eclipse, it is easier to see the earth's shadow as it slowly covers the moon's surface.
