halo orbit

名词 n.
中文释义

英文释义

名词 n.
  1. A periodic, three-dimensional orbit about any one of the Lagrange points L₁, L₂ or L₃ of a two-body gravitational system.
    — Due to the strong hyperbolic character of the halo orbits, the stable manifold approaches the halo orbit in a very fast way. This fact means that if we are able to put the satellite in the stable manifold of a halo orbit, it will be close to the halo orbit (say at [a] few km) in a reasonable period of time.

First used by NASA mission specialist Robert W. Farquhar in 1966 for calculated orbits around the Earth–Moon L₂ point which required the use of thrusters to be made periodic.
