A waxing gibbous Moon, rising over mountains with coniferous trees. The Moon's position relative to Earth and the Sun determines the moonrise and moonset time. For example, a last quarter rises at midnight and sets at noon. [5] A waning gibbous is best seen from late night to early morning. [6]
The Moon then wanes as it passes through the gibbous moon, third-quarter moon, and crescent moon phases, before returning back to new moon. The terms old moon and new moon are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the Sun and begins to wax ...
The word "gibbous," derived from the Latin word for "hump," refers to the convex shape. Over about a week's time, this phase marks the progression from a first quarter moon to a full moon. Full Moon

Best visible shortly before or after a new moon (during the waning and waxing crescent phases respectively), Earthshine is the faint glow of the non-illuminated (night) side of the Moon caused by sunlight reflecting off the surface of Earth (which would appear nearly full to an observer situated on the Moon at this time) and onto the night side ...
When the moon is nearly full, it is called a gibbous moon. The crescent and gibbous moons each last approximately a week. [5] Each phase is also described in accordance to its position on the full 29.5-day cycle. The eight phases of the moon in order: [5] new moon; waxing crescent moon; first quarter moon; waxing gibbous moon; full moon; waning ...
An astronomically correct crescent shape (shaded area), complemented by a gibbous shape (unshaded area). The crescent shape is a type of lune , the latter consisting of a circular disk with a portion of another disk removed from it, so that what remains is a shape enclosed by two circular arcs which intersect at two points.
It is a gibbous phase when it approaches or leaves the opposite side of the Sun. It shows a quarter phase when it is at its maximum elongation from the Sun. Venus presents a thin crescent in telescopic views as it comes around to the near side between the Earth and the Sun and presents its new phase when it is between the Earth and the Sun.
