When the moon is fully illuminated by the Sun What phase is this?
Full Moon
The Full Moon is when the Sun and the Moon are aligned on opposite sides of Earth, and 100% of the Moon’s face is illuminated by the Sun (see illustration). That said, some Full Moons are only 99.9% illuminated, as seen from Earth.
Which part of the moon is illuminated by the Sun?
The sun illuminates one side of the moon and leaves the other side in shadow. Anyone can see that the side of the moon facing towards the Sun is bright, and the side facing away from the sun is dark. As the moon orbits the Earth we see these lighted and dark parts of the surface in changing proportions.
What is the illuminated part of the moon called?
phases
The revolution of the moon around the earth makes the moon look as if it is changing shape in the sky. This is caused by different angles from which we see the lighted part of the moon’s surface. These are called phases of the moon.
What is the phase of the Moon when 100% of the Moon is lit up?

| Moon phase | Illuminated portion | Average moonrise time |
|---|---|---|
| Northern Hemisphere | ||
| Full Moon | 100% illuminated disc | 6 pm |
| Waning gibbous | Left side, (100%–50%) lit disc | 9 pm |

What is the phase when the entire lighted portion of the Moon is seen in the sky?
Full Moon: The lighted side of the Moon faces the Earth. This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the middle. The Moon that we see is very bright from the sunlight reflecting off it. Last Quarter: Sometimes called Third Quarter.
