Light from the sun is reflected off the moon back to the earth, which is why the moon looks illuminated.

Does a gibbous moon appears more than half illuminated to people on earth?

Yes. A gibbous moon is a three-quarter moon.


What portion of the moon is always illuminated?

Half of the Moon, just like Earth and the other planets, is more or less illuminated all the time. The half that is illuminated is the half that faces the Sun. The illuminated half continually changes as the Moon orbits and revolves. The exception is when the Earth gets between the Moon and the Sun, shading the Moon. (an eclipse).


How much of the moon is illuminated by the sun at each position as the moon orbits earth?

Half (50 percent) of the moon is illuminated by the sun at all times, just as half of earth is always illuminated.The thing that changes is: How much of the moon's illuminated half can we see from earth ?


Right half of moon is illuminated.?

When the right half of the moon is illuminated it would be called first quarter. (That's when you see the Moon from the northern hemisphere.)


Which side of the moon is illuminated the east or the west?

The side of the moon that is illuminated is always the side that is facing the sun. Whether you perceive that as facing east or west depends on the phase of the moon and the time of day that you observe it. If the moon is in its first quarter and you observe it in the evening, the side that faces west (toward the setting sun) is illuminated. If the moon is in its third quarter and you observe it in the morning, the side that faces east (toward the rising sun) is illuminated.

What percentage of the moon is illuminated during all lunar phases?

The percentage of the moon that is illuminated varies during different lunar phases. During a full moon, 100% of the moon is illuminated, while during a new moon, 0% is illuminated. The waxing and waning phases fall somewhere in between, with values from 1% to 99% illuminated.


What is the minimum percent of the moon that needs to be illuminated in order for the phase to be called gibbous?

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".
