AI overview

Libration is a slight rocking or wobbling motion that allows us to see slightly more than half of the Moon's surface over time, even though the same side always faces Earth. This matters because it means that from Earth, we can eventually observe about 59% of the Moon's surface rather than just 50%, giving us a more complete view of our nearest celestial neighbor.
