how much of the moon can we see
The other face, most of which is never visible from the Earth, is therefore called the far side of the Moon. Over time some parts of the far side can be seen due to libration. In total 59 percent of the Moon's surface is visible from Earth at one time or another. Useful observation of the parts of the far side of the Moon occasionally visible from Earth is difficult because of the low viewing angle from Earth (they cannot be observed full on).
