when the moon half shows itself, it's called a half moon.

∙ 11y agoThese are different phases of the moon based on its appearance as observed from Earth. Crescent moon is when less than half of the moon is visible, first quarter is when half of the moon is visible, waning gibbous is when more than half but less than full moon is visible, and waxing gibbous is the phase when more than half but less than full moon is visible.
gbfrveufbrg A good summary of the story "Moon Phases", (if I am talking about the same book as you are) is that there are many different phases of the moon. There is a crescent moon, full moon, half moon, and much more! (name all if necessary). The moon changes over time. The moon is always there in the day time, however, in the night it shines, so it's clearer to see, and more visible. :)
Depending on the cycle, it is a waxing or waning gibbous moon if it is more than half visible. If it's completely visible, it's a full moon.
The gibbous phase of the moon occurs when the moon is more than half full but less than completely full. It happens after the first quarter phase and before the full moon phase in the lunar cycle.
It sounds like the moon is currently waxing gibbous, with more than a quarter but less than half of the moon visible. As it progresses towards the third quarter phase, the visible portion will continue to decrease until only half of the moon is visible.
A moonless period is called "dark moon" or "new moon." During this time, the moon is positioned between the Earth and the sun, making it almost invisible from Earth because the side of the moon that is illuminated by the sun is facing away from us.

A gibbous moon is one of the phases of the Moon, when the size of the illuminated portion is greater than half but not a full Moon.
Depending on the cycle, it is a waxing or waning gibbous moon if it is more than half visible. If it's completely visible, it's a full moon.
That happens at the times of the First Quarter and Last Quarter phases. "Half moon" is actually not a bad description for what you see at that time. It's more than a crescent, but less than gibbous.

Craters on the moon are most visible when the sunlight hits them at a low angle, such as during the waxing or waning phases of the moon. This creates long shadows that make the crater edges more prominent.
The four major moon phases, which are about a week apart, arenew moon,first quarter,full moon, andlast quarter.As the amount of sunlight we see on the moon increases from new moon to full moon, the moon is said to be waxing. As that amount decreases from full moon to new moon, the moon is said to be waning. Also, when less than half of the visible side of the moon is lit, it is called a crescent, and when more than half is lit, it is called gibbous. Inserting into the list of moon phases the descriptions of the moon between phases gives us the following list:new moonwaxing crescentfirst quarterwaxing gibbousfull moonwaning gibbouslast quarterwaning crescent(new moon)
* Dark Moon - Not visible * New Moon - Not visible, or traditionally, the first visible crescent of the Moon * Waxing Crescent Moon - Right 1-49% visible * First Quarter Moon - Right 50% visible * Waxing gibbous Moon - Right 51-99% visible * Full Moon - Fully visible * Waning gibbous Moon - Left 51-99% visible * Third Quarter Moon - Left 50% visible * Waning Crescent Moon - Left 1-49% visible * New Moon - Not visible ref from http://www.answers.com/main/ntquery?s=moon+phases&gwp=13 Rob
During the waning crescent phase, the moon appears as a thin crescent and gradually decreases in size until it becomes a new moon, where it is not visible in the sky.
The waxing phase of the moon is the time when more of the moon is shown each night until it is a full moon. It then goes into its waning phase where less of it shows until it is a new moon where it is not visible in the night sky.
