In astronomy,
libration is an oscillating motion of orbit ing bodies relative to each other, notably including the motion of the Moon

libration point are curved paths that lie entirely in the plane of the two primary bodies.

libration.
Kaynak: Orbit of the Moon There are several classes of co-orbital objects, depending on their point of
libration . The most common and best-known class is the
Kaynak: Co-orbital configurationThat is,
libration (oscillation about a constant value) occurs in the argument of pericenter . The effect was described in 1961 by the
Kaynak: Kozai mechanismlocked, about 59% of the Moon's total surface may be seen with repeated observations from Earth due to the phenomena of
libration and parallax .
Kaynak: Tidal lockingThe existence of a photometrically confirmable concentration of dust at the
libration points was predicted by Professor J. Witkowski in

libration s have been made, and they have been generalized to treat other satellites and
