The most important and recent news of Saudi Arabia – Saudi News in the video .. “Al-Zaaq”: We do not see the dark part of the moon because of its rotation speed.
Astronomer Khaled Al-Zaq explained the reason for not seeing the dark part of the moon and seeing only the bright part of it.
“The moon has two sides, a lit face and a dark, lit face that the whole world sees, and the dark one only astronauts see, as it revolves around itself every 27 and a half days,” Al-Zaaq said during the “Calendar” segment.
And he continued: “The moon also revolves around the earth, so we can only see one part of it, which is the bright one, because the speed of the moon’s rotation around itself is equal to the speed of its rotation around the earth, like the one circling around the Kaaba.”
He added: “The moon is a dark body but reflects the sunlight falling on it. Our vision of the moon depends on the angle of view, so we see it as a crescent and a full moon.”
