Expansion request

Orbital elements says that a perturbed orbit can be modeled as a series of osculating orbits. It would be nice if this article explained how this is done, and provided some diagrams to illustrate. -- Beland (talk) 17:38, 1 December 2008 (UTC)[reply]

Central body fixed?

Is the central body assumed to be fixed or is the motion defined relative to the barycenter? —Preceding unsigned comment added by 90.229.231.115 (talk) 18:23, 3 February 2009 (UTC)[reply]
