Half moons are often referred to as quarter moons because they represent a phase in the lunar cycle where the moon is one-quarter of the way through its orbit around the Earth. This occurs when the moon is either in its first or third quarter, leading to half of its surface being illuminated by the Sun. The terminology can be confusing, as "quarter" refers to the position in the lunar cycle rather than the visual appearance of the moon.
It is called "first quarter" or "last quarter" when the moon is exactly half-lit.
The half moon is also called the "first quarter" or "third quarter" moon, depending on its phase. In the first quarter, the right half of the moon is illuminated, while in the third quarter, the left half is lit. This terminology refers to the moon's position in relation to the Earth and the Sun.
They are the same thing. "Half Moon" refers to half of the Moon's hemisphere that faces Earth being illuminated. That happens at one quarter and three quarters of the way through the Moon's phases. That's why we refer to the "first quarter" and the "third quarter" in the Moon's phases.
A moon that is larger than a quarter can be referred to as a "large moon" or simply a "moon." In astronomical terms, moons are typically classified based on their size, with larger moons often being called "large satellites." However, there isn't a specific term that universally defines moons based solely on their size relative to a quarter.
When the right half of the moon is illuminated it would be called first quarter. (That's when you see the Moon from the northern hemisphere.)
The moon's so-called "quarter" phases occur a quarter of a month (i.e. a week) before and after the New Moon. On each of those occasions, the moon appears half-full.
It is called "first quarter" or "last quarter" when the moon is exactly half-lit.
quarter Moon if its half of a sphere then its half moon
The half moon is also called the "first quarter" or "third quarter" moon, depending on its phase. In the first quarter, the right half of the moon is illuminated, while in the third quarter, the left half is lit. This terminology refers to the moon's position in relation to the Earth and the Sun.
This is the first quarter phase. The moon looks half lit, half in shadow, but you actually can only see one quarter of the moons surface at this point (during a full moon, you would only be able to see half of the moons surface - the half that faces us).
They are the same thing. "Half Moon" refers to half of the Moon's hemisphere that faces Earth being illuminated. That happens at one quarter and three quarters of the way through the Moon's phases. That's why we refer to the "first quarter" and the "third quarter" in the Moon's phases.
The waxing moon phase is when the moon is transitioning from new moon to full moon, and the illuminated portion of the moon is growing larger each night. During this phase, we can see more than half of the moon's lighted side from Earth.

quarter moon
A half moon is a lunar phase where half of the moon's visible surface is illuminated by the sun. This occurs when the moon is positioned at a 90-degree angle relative to the Earth and the sun. Half moons are also known as the first quarter moon or third quarter moon, depending on which side is illuminated.
That phase is called the third quarter or it could be called a waning half moon.
