The reason for the stability is a second-order effect: as a body moves away from the exact Lagrange position, Coriolis acceleration (which depends on the velocity of an orbiting object and cannot be modeled as a contour map) [22] curves the trajectory into a path around (rather than away from) the point.
L 4 is the Sun–Earth Lagrange point located close to the Earth's orbit 60° ahead of Earth. Asteroid (706765) 2010 TK 7 is the first discovered tadpole orbit companion to Earth, orbiting L 4 ; like Earth, its mean distance to the Sun is about one astronomical unit .
Lagrange point colonization is a proposed form of space colonization [1] of the five equilibrium points in the orbit of a planet or its primary moon, called Lagrange points. The Lagrange points L 4 and L 5 are stable if the mass of the larger body is at least 25 times the mass of the secondary body. [2] [3] Thus, the points L 4 and L 5 in the ...
The orbits for two of the points, L 4 and L 5, are stable, but the halo orbits for L 1 through L 3 are stable only on the order of months. In addition to orbits around Lagrange points, the rich dynamics that arise from the gravitational pull of more than one mass yield interesting trajectories, also known as low energy transfers. [4]
The trapped body will librate slowly around the point of equilibrium in a tadpole or horseshoe orbit. [10] These leading and trailing points are called the L 4 and L 5 Lagrange points. [11] [Note 1] The first asteroids trapped in Lagrange points were observed more than a century after Lagrange's hypothesis. Those associated with Jupiter were ...

A halo orbit is a periodic, three-dimensional orbit associated with one of the L 1, L 2 or L 3 Lagrange points in the three-body problem of orbital mechanics.Although a Lagrange point is just a point in empty space, its peculiar characteristic is that it can be orbited by a Lissajous orbit or by a halo orbit.

In classical field theories, the Lagrangian specification of the flow field is a way of looking at fluid motion where the observer follows an individual fluid parcel as it moves through space and time.
