2. Astronomy. A real or apparent motion of an oscillating kind. libration of the moon: an apparent irregularity of the moon's motion which makes it appear to oscillate in such a manner that the parts near the edge of the disk are alternately visible and invisible. (There are three kinds, called libration in latitude, libration in longitude, and diurnal or parallactic libration.)

1671 Philos. Trans. 1670 (Royal Soc.) 5 2061 Doubtless, as there is a certain Libration in the Moon, so 'tis not absurd to me, to hold a kind of Libration in the Earth, from the Annual and Diurnal motion of the same.

1678 J. Norris Coll. Misc. (1699) 181 We are nonplus'd at a thousand Phenomenas in Nature, which if they were not done, we should have thought them absolutely impossible, as for instance the central Libration of the Earth.
