How much of the moon is almost always in sunlight?

About 50% of the Moon's surface is almost always in sunlight at any given time. However, due to the Moon's synchronous rotation, which keeps the same side facing Earth, only the near side is visible from our planet. The far side of the Moon also receives sunlight, but it is not seen from Earth. Hence, while 50% is illuminated, we only see half of that illuminated surface from our perspective.
