Talk:Lissajous orbit

message: Could anyone please read over this article to check for (at least) basic correctness?  Thanks! Sdsds 01:31, 24 March 2007 (UTC)

message: I am really interested in space and orbits and orbital mechanics.  I have a (non-technical) doctorate degree. That said, I  can't make heads or tails of this article.  Should't it be written so that a non-scientist can get something out of it? Kjdamrau 03:46, 25 July 2007 (UTC)
thread_title:  WTF? 

message: I believe the Lissajous orbit is a more eccentric/complicated orbit than a halo orbit. However, the article describes it as non-coplanar in contrast to the halo orbit. The halo orbit is not coplanar to the two main masses (see my last sentence), in fact it's exactly perpendicular to the line between the masses. If the smaller mass were the earth, a halo orbit would trace a 'halo' above the earth around the Lagrange point, hence the name. I'd extend that to say that a Lissajous orbit would be a tilted and/or elliptical halo. 
I won't change the article though, as I have a suspicion that my understanding of the use of the word 'planar' isn't appropriate in this context :)  —Preceding unsigned comment added by AnitaBSc (talk • contribs) 01:53, August 26, 2007 (UTC) 
:Ha ha! I think you are right -- that a halo orbit is planar but out of the plane of the two larger bodies' orbits, and that a lissajous orbit is more complicated. I suspect a lissajous orbit may not even be planar, which would explain the strange wording about it being an "orbital trajectory". If only there were an available source for the math involved!

replies: text: I took the plunge!  "Coplanar" was just too confusing.  I've replaced it by first describing halo orbits as being in the perpendicular plane, then contrasting the Lissajous orbit.  Hope you find this an improvement.  Yoyo 124.191.50.199 19:11, 9 October 2007 (UTC)
thread_title:  Correctness 

message: The current diagram being used here is actually showing how to reach a Lissajous orbit, not the orbit itself.  --Lasunncty (talk) 19:20, 20 December 2013 (UTC)
replies: text: I think we could also benefit from having a diagram that shows all the points, as opposed to just L2. --Goatonastik (talk) 20:05, 17 March 2017 (UTC)

message: The Halo orbit article lists SOHO as being the second spacecraft to achieve a Sun-Earth L1 halo orbit. It's also listed here.  Has its orbit type changed?

replies: text:  According to the Earth Observatory Portal, SOHO is incorrectly listed here as having a Lissajous orbit.  The site explicitly refers to SOHO's orbit as a halo orbit and includes a schematic diagram of the orbit (https://directory.eoportal.org/web/eoportal/satellite-missions/s/soho).165.225.38.204 (talk) 14:10, 27 October 2017 (UTC)
thread_title:  SOHO? 

message: These asteroids are normally described as being "at" the L4 and L5 Lagrangian points. To be pedantic, that is only an approximation. More precisely, they in fact execute Lissajous and halo orbits around these points, with an enormous range of amplitudes.  — Preceding unsigned comment added by 58.166.224.167 (talk) 00:32, 3 March 2018 (UTC)

message: This simple animated graphic is an awesome illustration of quite a large number of the (apparently, quite odd) trajectories that can be seen in Lissajous orbits.  Lissajous orbit diversity, illustrated
This video] describes a couple of mathematicians who have done good illustrations of this type, as well as how a freeware (free software) program called "geogebra" that can facilitate drawing these Lissajous figures.  
Would be helpful if someone would care to generate a Creative Commons-licensed animated graphic for Wikipedia.  N2e (talk) 14:32, 17 June 2021 (UTC)
