A "gibbous" Moon has between 51% and 99% of the illuminated side of the Moon visible from Earth.
Just to be precise; the Moon is always 50% illuminated. The Moon is a rocky ball, half in sunlight and half in darkness. As the Moon orbits the Earth, the same face of the Moon is always visible. From the Earth, we see "phases" of the Moon as the Moon orbits the Earth. At the new moon phase, the illuminated half of the Moon is the "far side" of the Moon; at the full, the illuminated half is the "near side".
