the light shown because of the earth, as upon the moon, and matching to moonlight; -- called also earth shine.
The sunlight reflected from the earth toward moon, by which we come across faintly, when the moon is nearby the sun (either before or after brand-new moon), that area of the moon's disk unillumined by direct sunlight, or “the old moon in hands of new.”
Light mirrored because of the planet: just like earth-shine.
How would you define earthlight?
