So why a quarter moon? Nowhere in the dialogue above does 25% come into play! A quarter moon has nothing to do with seeing 25% of the moon’s surface illuminated or the moon’s floor being 25% illuminated. The moon’s floor is ALWAYS 50% illuminated. The phrase ‘quarter moon’ has to do with where in the lunar cycle the moon is. The start of a lunar cycle occurs when the moon is in its new part.

The brilliant full Moon within the sky makes it seems as if a considerable amount of light is mirrored off of the Moon’s surface. This will not be true. In truth, the Moon’s surface just isn’t very reflective in any respect. On average, only 7% of the Sun’s gentle that strikes the surface of the Moon is mirrored.

The bigger motive, nevertheless, is that you’re contrasting the complete Moon towards a dark sky. It’s that distinction that makes the Moon appear very brilliant. Compare a full Moon that rises as the Sun is setting to a full Moon a few hours later. The same amount of sunlight is reflecting off the Moon’s surface, yet the full Moon when the Sun is simply setting doesn’t appear almost as vibrant as the total Moon an hour later when it’s dark outside. This is as a result of contrast of the Moon on a darkish sky.
