An effect caused by the apparent wobble of the Moon as it orbits the Earth The Moon always keeps the same side toward the Earth, but due to libration, 59% of the Moon's surface can be seen over a period of time
(astronomy) a real or apparent slow oscillation of a moon or satellite; "the libration of the moon
The turning of the visible face of the Moon which allows observers on Earth to view more of the lunar surface around the limb
A real or apparent libratory motion, like that of a balance before coming to rest
