Lagrange Points also L-points, are the five positions in an orbital configuration where a small object affected only by gravity can theoretically be stationary relative to two larger objects (such as a satellite with respect to the Earth and Moon).
Lagrange Points (L1,L2)
In the Earth-sun system, the Lagrange Points (or equilibrium points) L1 and L2 are located on a line containing the Earth and sun with L1 between the Earth and sun and L2 beyond the Earth away from the sun.
LAGRANGE POINTS - Five points, labeled L1 through L5, in the vicinity of two massive bodies where each others' respective gravities balance.
Lagrange points- Lagrange showed that three bodies can lie at the apexes of an equilateral triangle which rotates in its plane; if one of the bodies is sufficiently massive compared with the other two, ...
Lagrange points
Points in the vicinity of two massive bodies (such as the Earth and the Moon) where each others' respective gravities balance. There are five, labeled L1 through L5.
Lagrange points -- Five points with respect to an orbit which a body can stably occupy. Designated L1 through L5. See Chapter 5.
LAN -- Local area network for inter-computer communications.
LAGRANGE POINTS
Lagrange points (named for Josef Lagrange, the Italian-French mathematician who discovered them) are a set of five special points that occur between two large objects.
Lagrange points are found in all gravitational systems with two large bodies and one small one. The important case for space colonization is the Earth-Moon system, with the space habitat as the third body.
Lagrange points are occasionally mentioned in science fiction (most often hard science fiction), but are rarely used as a plot device because Lagrange points are unfamiliar outside of the scientific or space-enthusiast community.

Figure 14.5 The Lagrange points of the Jupiter"Sun system, where a third body could orbit in synchrony with Jupiter on a circular trajectory. Only the L4 and L5 points are stable. They are the locations of the Trojan asteroids.
Trojan an object orbiting in the Lagrange points of another (larger) object. This name derives from a generalization of the names of some of the largest asteroids in Jupiter's Lagrange points: 588 Achilles, 624 Hektor, and 911 Agamemnon.
As of January 2007, five Trojans have been discovered in one of the stable (leading 60-degree or L4) Lagrange points of gravitational equilibrium in Neptune's orbit around the Sun.
Definition: Trojan: An object orbiting in the Lagrange points of another (larger) object.
I programmed a subroutine for optimization of in-space vehicles to develop the most efficient combination of stages for "flex path" missions to the moon, Lagrange points, an asteroid, near-Earth objects, Martian moons, Mars and Venus.

I suspect there is a reservoir but think it is premature to say much about it. We need more detections of related objects, and of course preferably of Trojans that stay very near the Lagrange points." ...
Instead, Tethys' co-orbiters S13 and S14 are located at the stable Lagrange points on Tethys' orbit, leading and following Tethys by 60, in a manner precisely analogous to the Trojan asteroids in Jupiter's orbit.
