Halo orbit - Wikipedia
A halo orbit is a periodic, three-dimensional orbit associated with one of the L1, L2 or L3 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. These can be thought of as resulting from an interacti… 展开
Definition and historyRobert W. Farquhar first used the name "halo" in 1966 for orbits around L2 which were made periodic using thrusters. Farquhar advocated us…
- A halo orbit is a periodic, three-dimensional orbit near one of the L 1, L 2 or L 3 Lagrange points in the three-body problem of orbital mechanics1. It is called a "halo" orbit because the tracked orbit looks like a halo around the moon2. The Gateway can sit in this halo orbit, requiring little energy for stationkeeping or to maneuver into other cislunar orbits2. The SOHO spacecraft is in a halo orbit around the Sun – Earth L1 point3.了解详细信息：✕以上信息汇总借助人工智能技术，若访问原文请查看了解详细信息。

In orbital mechanics a near-rectilinear halo orbit (NRHO) is a halo orbit that passes close to the smaller of two bodies and has nearly stable behavior. The CAPSTONE mission, launched in 2022, is the first spacecraft to use such orbit in cislunar space, and this Moon-centric orbit is planned as a staging area for future lunar missions. In contrast with low lunar orbit which NASA characterize…
