In today's world, each and everyone is quite aware of the fact that Moon Is The Natural Satellite Of The Earth which revolves around the Earth in approx 27.32 days which is also known as the Lunar Month. While revolving around the Earth, only half of the Moon's surface gets illuminated by the Sunlight because of the Astronomical Phenomena known as the Synchronous Rotation or Tidal Clocking making day and night on the Moon.

The Sun lits the Moon as well as the Earth. As the Moon orbits around the Earth, how much light we can see from our earthly point of view are known as the Phases Of The Moon or Lunar Phases Of The Moon. In simple terms, every day we observe the changing size of the moon; is scientifically known as the Phases Of The Moon or Lunar Phases Of The Moon


Why Does The Moon Changes Its Shape?

The Moon's shape changes mainly due to the following reasons:


  1. The Moon orbits around the Earth.
  2. The Moon and the Earth orbits around the Sun.
  3. The Sun lits or illuminates both Earth and the Moon because both Moon and the Earth reflect light from the Sun. 
  4. The Moon's Lunar Phases or Phases Of The Moon are produced due to the alignment of the Moon and the Sun in the sky.
  5. The half part of the Moon facing the Sun is illuminated and on the other hand, the half part facing away the Sun is always in the darkness (The Dark Side Of The Moon) due to the astronomical phenomena known as Synchronous Rotation or Tidal Clocking; that's why we only get to see one side of the Moon ever. 


8 Lunar Phases Of Moon

The Lunar Phases Of The Moon are cyclic in nature starting from the new moon to full moon in approx 27.32 days. There are 8 Lunar Phases Of The Moon that occurs at a specific location on the Moon's Orbit. Technically, The Lunar Month can be divided into 4 Primary Phases that are:- New Moon, First Quarter Moon, Full Moon, Last Quarter Moon; and 4 Secondary Phases that are:- Waxing Crescent Moon, Waxing Gibbous Moon, Waning Gibbous Moon and Waning Crescent Moon.

Now, Let's Get To Know Each Lunar Phases One By One

1. New Moon

A New Moon is the first phase of the Lunar Month Cycle which occur when the moon comes between the Earth and the Sun. During a new moon day, the side of the moon facing earth is not illuminated by the sunlight due to the alignment between the sun and the moon. Only on a new moon day, a Solar Eclipse can occur.


2. Waxing Crescent Moon

When the bright part of the moon is getting bigger, the lunar shape of the moon is waxing or growing into its crescent phase; what we call is A Waxing Crescent Moon. It is also known as a Young Moon.

Sometimes during the waxing crescent phase of the moon; rest of the moon is also faintly visible because of the reflection of sunlight from earth to the moon. This astronomical phenomenon is known as Earthshine.




3. First Quarter Moon

First quarter means the moon is one-fourth of the way around the earth; hence the name "First Quarter Moon". It generally occurs one week after the new moon. Sometimes, it is also called as Half Moon; as we see exactly half (right side) of the illuminated portion of the Moon's Lunar Surface.


4. Waxing Gibbous Moon

When the moon's lunar surface is more than half-lit or illuminated, A Waxing Gibbous Moon occurs. A lunar shape is getting bigger (waxes). It occurs between the first quarter moon phase and the full moon phase. A waxing gibbous moon's phase is larger than the semi-circle but quite smaller than the full circle.


5. Full Moon

A full moon day is observed when the entire moon's surface is lit or illuminated by the sunlight. It occurs when the moon is totally on the opposite side of the earth. On full moon day, the moon looks like a complete circle. Only on a full moon, a lunar eclipse can occur.


6. Waning Gibbous Moon

After the full moon day is observed, the lunar shape of the moon starts to get smaller (decrease) that means the moon is waning; A Waning Gibbous Moon Occur. A waning gibbous moon is also regarded as the reverse of the waxing gibbous moon. It occurs between the full moon phase and third quarter phase.




7. Third Quarter Moon

After the appearance of the glorious full moon, the moon starts to wane (decrease or getting smaller); the third quarter moon occurs. Third quarter means the moon is three-fourths of the way around the earth; hence the name "Third Quarter Moon"

The third quarter moon is also regarded as the reverse of the first quarter moon. Sometimes, it is also called as half moon; as we see exactly half (left side) of the illuminated portion of the moon's lunar surface.

8. Waning Crescent Moon

The last lunar phase of the moon before returning to the new moon phase is known as the waning crescent moon. When the bright part of the moon is getting smaller, the lunar shape of the moon is waning or decreasing into its crescent phase; what we call A Waning Crescent Moon.

By the end of the 27.32 days Lunar Month Cycle, the moon has vanished almost entirely. And we are again back to the new moon to start again the ever repeating cycle.


ON that note, I can say that I have tried to give an overview of 8 Lunar Phases Of Moon - From New Moon To Full Moon To New Moon within my reach. If there is any suggestion, I am all ears. Feel free to comment.
