Doesn't every part of the Moon get some sunlight over the lunar cycle?
- RichWalton 6y agoSome parts of some craters are in permanent shadow.
- cgriswald 6y agoThis is true, but the phrasing "might be present on the sunlit side of the Moon" is problematic and reinforces the belief (also reinforced by the phrase "dark side") that the Moon has a light and dark side. (At least in the case of 'dark side' an argument could be made that it means 'dark to (historical) human knowledge.' It's hard to defend "sunlit side.")

- pulkitanand 6y agoTidal forces from Earth have slowed the Moon's rotation to the point where the same side is always facing the Earth—a phenomenon called tidal locking. https://en.wikipedia.org/wiki/Far_side_of_the_Moon https://en.wikipedia.org/wiki/Far_side_of_the_Moon
