alterations to an object's orbit caused by gravitational interactions with other bodies
- The orbit as such is caused mainly "by gravitational interactions with other bodies". Andres 09:06, 21 September 2007 (UTC)
True enough. I have modified the article following your comment, as such: alterations to an object's orbit caused by gravitational interactions with bodies external to the system formed by the object and it parent body [. . .] CielProfond (talk) 23:40, 24 October 2008 (UTC)
This article needs to feature the Lagrangian and Gaussian perturbation equations and perhaps some explanation of how they're applied and/or derived. This is essential to understanding the topic beyond a popular level. Ryan Hardy (talk) 06:04, 24 February 2010 (UTC)
Presently "Orbital perturbation" redirects to "Perturbation (astronomy)". But I have added some stuff and plan to add some more that probably applies more directly to spacecraft orbit then to natural astronomical objects. Main difference is that spacecraft have a short orbital period and therefore have a rather constant environment for several successive orbits while the orbital periods of the different planets are of a similar magnitudes and the perturbation analysis for planets should therefore have a somewhat different characteristics.
Anyway, what had been put in the article until now was really thin!
I would like to revive "Orbital perturbation"! Or if astronomers prefer to have two articles, "Orbital perturbation (Astronomy)" and "Orbital perturbations (Spacecraft)". The latter with a lot of information of importance for "Orbit control" and "Mission design"
- I have solved the problem by starting a new article with the suitable name Orbital perturbation analysis (spacecraft)
- I definitely think it should be kept, at least until we see how the spacecraft article evolves. We still need a non-technical explanation, perhaps through examples, about how planetary perturbations occur in the Solar System. -- Kheider (talk) 19:42, 14 February 2011 (UTC)
F.R. Moulton wrote a minimal-math chapter on perturbations in his An Introduction to Celestial Mechanics. I could attempt to condense it for this article, although it relies on heavy use of diagrams, and I don't know how to do that here! I would like to see this article fleshed out a little in the descriptions of general and special perturbations. Tfr000 (talk) 15:59, 10 February 2012 (UTC)
