Once I heard that from earth we can observe about 60% of moon’s surface. Though the face that is turned to use os always the same. Is it true? And if so why?
In: Earth Science
The moon is tidally locked to the Earth, so that as it rotates around us, the same side of the moon always faces the Earth. The why is kind of complicated, but lets just say that the moon’s core is lopsided, and the heavier part of the core always faces Earth due to gravity.
From our vantage point here on Earth, we can see about 60% of the surface as the moon orbits us. The far side of the moon (wrongly called the dark side of the moon), always faces away from us, so in order to see that 40%, we had to send a camera back there on a rocket.
