What are the sun, moon, and star faces called?
The sun and the stars have no "named" faces.
The Moon has two "faces" only due to the fact that the Moon is tidally locked to Earth. That means that it only ever shows one side to the Earth. We therefore call the side we see the "near" side, and the side we don't see the "far" side. All of this happens because the moon's rotation (the time it takes to revolve around itself) has the same period as it's orbit around the Earth.
