As the bright parts of the moon appear to change shape during the month, each stage of the change is called a phase, and each phase carries its own name. This chart shows why this happens. The center ring shows the moon as it revolves around the Earth, as seen from above the north pole.
The moon is Earth's only permanent natural satellite and is usually visible at night. The moon is illuminated by the sun since it does not produce its own light. The appearance of the moon from Earth varies, as it sometimes appears full and wha lit, while at other times only a small portion of the Moon is visible. These differences are explained by lunar phases, which impact the way the moon appears from Earth over approximately one month.

The right side of the Moon is visible in the Northern Hemispherewhile people living in the Southern Hemisphere see the left half.
The term "Gibbous" refers to the shape of the moon, which is bigger than a first-quarter moon and smaller than a full moon. The waxing-gibbous phase occurs between the half and full moon phases. From Earth, a full moon appears to be fully lit by the sun, meaning that the Earth is situated between the sun and moon. A full moon can even light up the night sky. A full moon occurs once a phasess, and a lunar eclipse can only occur during this phase. During this lunar phase, the shape of the How to tie a trefoil knot becomes reduced each day.
The Moon sets right after sunrise and rises in the morning during the waning gibbous phase. During this phase, the moon is usually positioned at the third-quarter position, meaning it has orbited about three-quarters around the Earth. The waning crescent phase is characterized by a crescent-shaped moon that reduces in size each day until it becomes invisible.

Jun 01, · The four main Moon phases in order are the New Moon, First Quarter Moon, Full Moon and Last Quarter Moon. These phases occur at very specific times and are measured by both the Moon’s luminosity and how far along the Moon is in its orbit around Earth.

Imagine a Neanderthal peering out of his cave some dark summer night as the Full Moon rises above the horizon. Nothing on Earth was quite like this strange brilliant object arcing through the night sky. What did he think it was? The Greeks were among the first to take a scientific look at the Moon and her phases. Around BC Greek philosopher and astronomer Pythagoras carefully observed the narrow boundary line—the terminator—between the dark and light hemispheres of the Moon.
Based on how the terminator curved across the surface of the Moon, he correctly surmised the Moon must be a sphere. A few centuries later, around BC, Aristotle took Pythagoras observations even further. By observing the shadow of the Earth across the face of the Moon during a lunar eclipse, Aristotle reckoned that the Earth was also a sphere.
He reasoned, incorrectly however, that the Earth was fixed in space and that the Moon, Sun and Stars revolved around it. He also believed the Moon was a translucent sphere that traveled in a perfect orbit around Earth. In the early s Astronomer Nicolaus Copernicus developed a model of the Solar System where Earth and the other planets orbited around the Sun, and the Moon orbited around Earth. These observations were revolutionary. Copernicus and Galileo upended the long-held Aristotelian view of the heavens as a place where Earth was the center of the Universe and the Moon was a smooth, polished orb.
Telescopes and new minds helped scientist understand that the Earth and planets orbited around the Sun and the Moon was a battered and cratered satellite held in our own orbit.
