How long does a lunar day last for any location on the Moon, including the far side?
Answer
About 14 Earth days
A lunar day, defined as the period during which a specific location on the Moon receives sunlight, lasts for roughly 14 Earth days. This period is immediately followed by an equally long lunar night, lasting another 14 Earth days. This cycle applies uniformly to both the near side and the far side because the Moon rotates, ensuring that every part of its surface is exposed to solar illumination sequentially. The confusion regarding the far side's illumination status stems from the fact that while it receives sunlight, it never faces Earth simultaneously.
