THe Earth and Moon are tidally locked, right? So does that mean, if the Earth were a sun, that one side of the moon would NEVER face the sun? Thanks!!!
Yes, you have it right! As the Moon is tidally locked to Earth, only one side of the Moon would faced the Earth, while the other does not.
However, it is possible that looooong ago in the past, the Moon wasn’t yet tidally locked to Earth, so this may not have been the case forever!
