Can we see the same amount of illuminated side of the moon from earth?

No, we cannot see the same amount of the illuminated side of the Moon from Earth at all times. This is due to the Moon's synchronous rotation, where it takes the same amount of time to rotate on its axis as it does to orbit the Earth. As a result, we always see the same side, known as the "near side," while the "far side" remains hidden from view. However, the appearance of the illuminated portion changes with the lunar phases as the Moon orbits the Earth.
