'''Lagrange points''' are locations in space where gravitational forces and the orbital motion of a body balance each other. They were discovered by French mathematician [[Wikipedia:Joseph Louis Lagrange|Joseph Lagrange]] in 1772 in his gravitational studies of the 'Three body problem': how a third, small body would orbit around two orbiting large ones. There are five Lagrangian points in the [[Sol system|Sun-Earth]] system and such points also exist in the [[Earth]]-[[Luna|Moon]] system. | '''Lagrange points''' are locations in space where gravitational forces and the orbital motion of a body balance each other.
