Lagrangian point :
Lagrangian point is a point in space at which a small body, under the gravitational influence of two large ones, will remain approximately at rest relative to them.

The other two Lagrangian points, L4 and L5, are on the Earth's orbit, with the lines linking them to the Sun making 60° angles with the Earth-Sun line.

Lagrangian Points
Five points in the orbital plane of two massive particles in circular orbits around a common center of gravity, where a third particle of negligible mass can remain in equilibrium.

Lagrangian Point
Points of stability in the orbital plane of a binary system, planet, or moon. One is located 60 degrees ahead and one 60 degrees behind the orbiting bodies. Another is located between the orbiting bodies.

Lagrangian points. Five places where small bodies can exist in stable orbits in the plane of two larger bodies.

Lagrangian points are the stationary solutions of the circular restricted three-body problem.

Lagrangian point (NASA SP-7, 1965) One of the five solutions by Lagrange to the three-body problem in which three bodies will move as a stable configuration.

The first would work with a space telescope, most likely positioned near the Earth's L2 Lagrangian point. The second would place the satellite in a highly elliptical orbit about the Earth, and work in conjunction with a ground telescope.

One hypothesis is that Theia formed at a Lagrangian point relative to Earth, that is, in about the same orbit and about 60° ahead or behind.

Lagrangian point One of the solutions to the three-body problem discovered by the eighteenth century French mathematician Lagrange; the two stable Lagrangian points, L-4 and L-5, lie in the orbit of the primary body, ...

These are positions (now called Lagrangian points and designated L4 and L5) where a small body can be held, by gravitational forces, ...

Although the Trojans are stabilized at the Lagrangian points by gravitational interactions with Jupiter and the Sun, their actual distribution is elongated along the orbit.

In 1906 Max Wolf discovered 588 Achilles near the Lagrangian point preceding Jupiter in its orbit.

It was inserted into a halo orbit around the L1 Lagrangian point between the Earth and Sun in February 1996.

To keep the array of transmitters in phase despite the planet rotating (unless the transmitters are located in space, perhaps at the L1 Lagrangian point, which would avoid any attenuation by a planetary atmosphere, at least on the transmitting end) ...

The Trojan asteroids are two families of asteroids stationed at the Lagrangian points in Jupiter's orbit. The first one discovered was 588 Achilles but the largest is 624 Hektor.

Trojan satellites
satellites which orbit at the Lagrangian points, 60° ahead of and 60° behind another satellite. For example, Telesto and Calypso are trojans of Saturn's satellite Tethys.

In astronomy, the adjective 'trojan' refers to a minor planet or natural satellite that shares an orbit with a larger planet or moon, but does not collide with it because it orbits around one of the two Lagrangian points of stability, L4 and L5, ...

Consider a system with the two large bodies being the Earth orbiting the Sun. The third body, such as a spacecraft, might occupy any of five Lagrangian points: ...

It will be located at the unstable L2 Lagrangian point, and will have a large sunshield to cool the telescope's IR optics. The sunshield, acting like a solar sail, will also have the role of helping to stabilize JWST in its L2 location.

While other possibilities have not been ruled out, simulation results are in good agreement with the observation that concentrations of dust that have been collected into librating orbits about the L4 and L5 Lagrangian points, ...
