Definition from
astronomy.com:
The small oscillations in the moon’s motion that allow Earth-based observers to see slightly more than half the moon’s surface
Example sentences:
Libration is the apparent side to side rocking and up and down nodding of the Moon. There are two components: the more obvious "optical" and the very subtle "physical" libration. (www3.telus.net)
Although the Moon always presents us with the same face towards the Earth, due to its rotation and revolution being tidally locked to the same period, the combined effect of all these different librations allows us over time to see some 59% of the Moon's surface. (Wertern Washington University)
Libration in longitude is a consequence of the Moon's orbit around Earth being somewhat eccentric, so that the Moon's rotation sometimes leads and sometimes lags its orbital position. (NationMaster.com)

Libracija
Definition from
hr.wikipedia.org:
Libracija je promjena orijentacije Mjesečeve površine u odnosu na motritelja na Zemlji.
Example sentences:
Pojava zbog koje, iako se može reći da Mjesec uvijek okreće Zemlji istu stranu (vidi sinkrona rotacija), Možemo vidjeti 59% Mjesečeve površine. Libracija u širini uzrokuje priklon Mjesečeva ekvatora prema ravnini njegove staze (6°40´), pa se vidi mali dio područja «iza» njegovih polova. Libracije u duljinu uzrokuje nejednolika brzina Mjesečeve revolucije (zbog eliptičnosti putanja), pa se vidi mali dio «iza» njegovog istočnog, odnosno zapadnog ruba diska. Dnevna ili paralaktička (vidi paralaksa) libracija uzrokovana je Zemljinom vrtnjom koja dovodi do različitog položaja promatrača na Zemlji. (Astronomsko društvo Korenica )
