If a quarter moon is so called because it is a quarter of the way around the earth, then a full moon is only half way around and should be called a half moon. The naming of the phases is unnecessarily illogical. At a minimum, a full moon is the second quarter; the third quarter is really the first quarter on the flipside.

Hi Bill, more food for thought …

Maybe it’s called a quarter moon because we’re only seeing a quarter of the entire globe of the moon.

Maybe it’s called a quarter moon because it’s one quarter of the way around in its orbit, as measured from one new moon to the next.

The origins of this name seem lost in history. I’ve never heard anyone answer this definitively.

All the best,

Why is this called a quarter moon? When it is full, it should be called a half moon if this is called a quarter moon. Just some words for thought. :)

To Mohammad T. Al-Tamimi: You asked “if moon in this picture (above) is set at right angle to a line between Sun and Earth, we have to observe the shadow of Earth on moon look like concavity. why we observe this shadow (on this picture) as a straight line?

You would only see the shadow of earth on the moon if earth were in the middle (causing an eclipse). When our Moon is in the middle it is like holding a ball between you and a lamp. Try it and see what it looks like. I hope this answered your question.
