A week after the new Moon we see half the moons face lit up it looks like a semi circle this phase is called what?

A week after the new Moon, when half of the Moon's face is illuminated, it is called the First Quarter phase. During this phase, the Moon appears as a semi-circle, with the right half lit up in the Northern Hemisphere. This occurs as the Moon moves in its orbit and more of its surface becomes visible from Earth.


What is the picture of 8 phases of moon?

Phase 1 - New Moon - The side of the moon that is facing the Earth is not lit up by the sun. At this time the moon is not visible.Phase 2 - Waxing Crescent - A small part (less than 1/2) of the moon is lit up at this point. The part that is lit up is slowly getting bigger.Phase 3 - First Quarter - One half of the moon is lit up by the sun at this point. The part that is lit up is slowly getting bigger.Phase 4 - Waxing Gibbous - At this time half of the moon is lit up. The part that is lit is slowly getting bigger. Waxing means to slowly get bigger.Phase 5 - Full Moon - The side of the moon that is lit up by the sun is facing the Earth. The entire moon is lit up at this point.Phase 6 - Waning Gibbous - The moon is not quite lit up all the way by sunlight. The part of the moon this is lit is slowly getting smaller. Waning means to slowly get smaller.Phase 7 - Last Quarter - Half of the moon is lit up but the sun. The part that we can see lit up is slowly getting smaller.Phase 8 - Waning Crescent - A small part of the moon is lit up at this point. It is getting smaller by the minute.


Is half the moon lit up by the sun?

I think this person means changing phases and don't worry I'll make my answer as true and clear as it can be. Yes half of the moon is lit up. except when eclipses occur it is lit up by the suns reflected light.


Why can only some of the moon be seen at one time?

Half of the moon is always lit up by the sun at any given time, and the moon orbits the Earth so us observers on Earth will see different amounts of the moon lit up. These different "shapes" we see are called the phases of the moon.


When the moon is completely lit up what is it called?

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.

How much of the whole moon are you seeing when half of the moon appear to be lit?

You can often see the entire "near side" of the Moon, because even though the sunlit half is very bright, the other part is dimly lit by reflected Earthlight. However, the official answer to your question is probably "one quarter". You can only see one-half of the Moon, and only half of that is lit up by the Sun.

It is called the eclipse
