No. Only half of the moon is illuminated at any one time. During a full moon, the half facing Earth is fully illuminated.
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.
One week after the full moon, the moon is in its third quarter phase. During this phase, the left half of the moon appears illuminated when viewed from the Northern Hemisphere, while the right half appears illuminated from the Southern Hemisphere. This is because the sunlight is shining on the opposite side of the moon compared to the full moon phase.
During a full moon, the moon is on the opposite side of Earth from the sun, with the Earth positioned between the two bodies. This alignment results in the moon being fully illuminated by the sun, appearing as a complete circle from our perspective on Earth.
A new moon - is when the moon's disc is completely in the shadow of the Earth. A full moon - is when the whole of the moon's surface is illuminated by the sun. Lunar eclipses can only occur during a full moon. Solar eclipses only occur during a new moon.
During a full moon, the Earth is positioned between the sun and the moon, allowing the entire illuminated side of the moon to be visible from Earth. In contrast, a full Venus (or superior conjunction) occurs when Venus is on the opposite side of the sun from Earth, making it difficult to observe because its illuminated side faces away from us. Thus, while we can see the full moon clearly, a full Venus is not visible from Earth.
There are two separate things that need to be addressed. One is the surface area of the Moon. The other is the surface area of the NEAR SIDE of the Moon. As a sphere in space, the Moon is always 50% illuminated, except during lunar eclipses. The phases of the Moon measure what percentage of the NEAR SIDE of the Moon is illuminated. At the new moon, none of the near side is lit up; at the full moon, 100% of the near side is illuminated.
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.
A Waxing Gibbous occurs when the moon is illuminated between a First Quarter and a Full Moon, during the second half of the moon's cycle. It appears as a larger part of the moon illuminated, but not yet full.
During a full moon, the side of the moon facing Earth is fully illuminated by the sun, making it appear as a complete circle from our perspective. The side not facing Earth is in shadow, causing us to only see the illuminated side during a full moon.
Mare Crisium is illuminated from a few days after the New Moon until a few days after the Full Moon.
The waxing phase of the moon is the period of time between new moon and full moon, where the size of the illuminated portion of the moon is increasing. The waning phase of the moon is the period of time between full moon and new moon, where the size of the illuminated portion of the moon is decreasing.
bright illuminated means lit up or full of light
You will see most of the moon's surface during the full moon phase when the entire illuminated side of the moon is facing Earth.
The Moon is not visible at the new moon phase. At the first quarter, it is "waxing" - the illuminated portion is increasing. At the full, the illuminated portion of the Moon is 100%, and it is finished waxing and is about to begin "waning", when the illuminated part is decreasing. At the 3rd quarter, it is waning.
The waxing gibbous is illuminated on the right and has its "horns" on the left, and so is shaped rather like this ). The waning gibbous, on the other hand, is illuminated on the left and has its "horns" on the right, and so is shaped rather like this (. (Comment: That's only if you're in the northern hemisphere.)
Full Moon
The period between a full moon and a new moon is approximately two weeks, known as a lunar cycle. During this time, the moon transitions from being fully illuminated to completely dark before beginning to wax again.
