Dark Side of the Moon

  • People usually say that “the dark side of the moon” while referring to the lunar face that can՚t be seen from the earth, it always refers to the far side of the moon, which despite pointing away from the earth sees as much sunlight as the side facing the earth.
  • Therefore, the dark side of the moon isn՚t dark, because it exists is due to a physics phenomenon known as the tidal locking. In the next few sections, we will be getting into more details about it.
Dark Side of the Moon

What is the Dark Side of the Moon?

  • Whenever one look at the sky in the night to see the moon, it appears the same every time.
  • No matter how one sees the moon or from where one sees the moon, it always seems to feature the same landscape.
  • The side of the moon which we are never able to see being on earth is known as the ‘dark side of the moon.’
  • It will be wrong to say that this side which is considered as the dark side of the moon is dark in color.
  • This side never faces the earth and is visible only from space.

Dark Side of the Moon Discovery

Dark Side of the Moon Discovery
  • As the Moon Rotates Around the Earth, and the Earth Around the Sun, the Moon is Exposed to the Sun՚s Light Just as the Earth is.
  • It is Easy to See Why People Think One Side of the Moon is Always in the Dark, Because It is Tidally Locked, the Same Side of the Moon is Always Exposed to the Earth.
  • Though the 28-Day Lunar Cycle Means That at Some Point, Every Side of the Moon is Exposed to Sunlight.
  • This Can Be Seen with the Lunar Phases, as During a New Moon, the Side of the Moon Exposed to Sunlight It the Opposite Side That is Exposed to the Earth.
  • There Simply is No Ever-Dark Side of the Moon, and It՚s Not Because It՚s All Dark, as Pink Floyd Claims.

Why Can՚t We See the Dark Side of the Moon?

  • We cannot see the dark side of the earth because the moon is tidally locked to the earth.
  • The earth rotates on its axis continuously and so does the moon. The time required by the Moon to rotate about its axis exactly matches to the time needed for orbiting the earth since earth and moon is tidally locked.
  • In simple words, the rotational period and the orbital period of the moon is the same.
  • So, we can see only one side of the moon. In other words, we can say that due to the sync in rotation and revolution of earth and moon, only one side of the moon always faces the earth, thereby another side which is never seen by us is called the dark side.

What is the Temperature on the Moon?

  • When the sunlight reaches the surface of the moon, the temperature is and when the sun goes down, the temperature is .
  • On the moon, day time lasts for 13.5 days and night time lasts for 13 days.
