Osculating orbit

Osculating orbit (inner, black) and perturbed orbit (red)

In astronomy, and in particular in astrodynamics, the osculating orbit of an object in space at a given moment in time is the gravitational Kepler orbit (i.e. ellipse or other conic) that it would have about its central body if perturbations were not present. That is, it is the orbit that coincides with the current orbital state vectors (position and velocity).
