Full Moon
Before the new moon, less of the moon is lit up when viewed from Earth.After the mew moon, more of the moon is lit up when viewed from Earth.
Half of the moon is always lit by the sun, unless the sun is eclipsed by the Earth. The portion of the illuminated moon viewed from Earth depends on the moon's orbit. As the moon orbits, different portions of shadow and illumination are seen from Earth, creating the moon's phases.
When the moon is half lit on the left side, it is called the "Last Quarter Moon" or "Third Quarter Moon." This phase occurs when the moon has completed three-quarters of its orbit around the Earth, resulting in the left half being illuminated as viewed from Earth.
Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth. We only see the Moon because sunlight reflects back to us from its surface.
In a gibbous moon phase, most of the moon that we see is lit.
About half of the moon is always lit by the sun. This is because only one half of the moon is visible from Earth at any given time. The amount of light that can be seen from Earth reflects different phases of the moon as it orbits.
When the moon is completely lit up, it is called a full moon. This occurs when the Earth is between the sun and the moon, causing the moon's entire sunlit side to be visible from Earth.
One hemisphere is always lit except when the moon is occulted by the earth.

The amount of the moon that is illuminated by the sun varies as the moon orbits Earth. At any given time, half of the moon is lit by the sun, but we can see different portions of this lit side from Earth depending on the moon's position in its orbit.
