Astrodynamics; the study of the movement of vehicles in space.

In the restricted three-body problem, a curved path around a Lagrangian point that lies entirely in the plane of the two primary bodies.

A quasiperiodic orbital trajectory that an object can follow around a Lagrangian point of a three-body system without requiring any propulsion.

plural of Lyapunov orbit

plural of Lissajous orbit

(astrodynamics) A sun-synchronous orbit.

A theoretical type of orbit which goes in a straight-line, up and down; with 100% orbital eccentricity (eccentricity=1.0); the orbital path passing through the center-of-mass of the primary mass being orbited; having an periapsis at 0, and two apoapsides, as both arms going out from the periastron are equidistant; where the orbital ellipse has zero width semi-minor axis/minor axis, and the path of the ellipse is the same as the major axis.

plural of halo orbit

(physics, orbital mechanics) A periodic, three-dimensional orbit about any one of the Lagrange points L₁, L₂ or L₃ of a two-body gravitational system.

(anatomy) Relating to the zygomatic arch and the orbit.
