Lagrangian point

Also found in: Encyclopedia, Wikipedia.

La·gran·gi·an point

Astronomy Any of five points in the orbital plane of two bodies, one of which is much larger than the other, at which a third, even smaller body will remain in gravitational equilibrium. Bodies located at Lagrangian points appear stationary with respect to the larger two bodies. Also called Lagrange point.

[After Comte Joseph Louis Lagrange.]

Lagrangian point

(Astronomy) astronomy one of five points in the plane of revolution of two bodies in orbit around their common centre of gravity, at which a third body of negligible mass can remain in equilibrium with respect to the other two bodies
