Libration
(gcide) | Libration \Li*bra"tion\ (l[-i]*br[=a]"sh[u^]n), n. [L. libratio:
cf. F. libration.]
1. The act or state of librating. --Jer. Taylor.
[1913 Webster]
2. (Astron.) A real or apparent libratory motion, like that
of a balance before coming to rest.
[1913 Webster]
Libration of the moon, any one of those small periodical
changes in the position of the moon's surface relatively
to the earth, in consequence of which narrow portions at
opposite limbs become visible or invisible alternately. It
receives different names according to the manner in which
it takes place; as: (a) Libration in longitude, that
which, depending on the place of the moon in its elliptic
orbit, causes small portions near the eastern and western
borders alternately to appear and disappear each month.
(b) Libration in latitude, that which depends on the
varying position of the moon's axis in respect to the
spectator, causing the alternate appearance and
disappearance of either pole. (c) Diurnal or parallactic
libration, that which brings into view on the upper limb,
at rising and setting, some parts not in the average
visible hemisphere.
[1913 Webster] |

Libration point
(gcide) | Libration point \Li*bra"tion point`\ (l[-i]*br[=a]"sh[u^]n
point`), n.
any one of five points in the plane of a system of two large
astronomical bodies orbiting each other, as the Earth-moon
system, where the gravitational pull of the two bodies on an
object are approximately equal, and in opposite directions. A
solid object moving in the same velocity and direction as
such a libration point will remain in gravitational
equilibrium with the two bodies of the system and not fall
toward either body.
