* The moon is tidally locked: The moon is tidally locked to Earth, meaning the same side always faces us. The "far side" of the moon, the one we never see from Earth, is still exposed to sunlight just as much as the near side.
* The moon's rotation: The moon rotates on its axis at the same rate it orbits Earth. This synchronized motion is why we only see one side. But this rotation means the entire surface of the moon, both near and far side, gets illuminated by the sun during its lunar day.
So, when the sun shines on the far side of the moon, it's just like a regular day for that side. It experiences:
* Sunlight: The surface warms up due to the sun's energy.
* Shadows: Features on the lunar surface cast shadows, just like on Earth.
* Variations in light: The sun's position changes over time, leading to variations in the amount and angle of sunlight hitting the far side, just like any other part of the moon.
The only thing that's different is that we can't see the far side of the moon from Earth, so we don't directly observe these events.
