==Application in orbital Mechanics==
For a given value d for a [[transfer obit]] which is the sum of the distance for each foci to a point on the [[ellipse]] of the transfer orbit, it can be shown that the second foci is the intersection of a circle centered at the departure point (e.g. [[Earth]]) and an intersection of a circle centered at the arrival point (e.g. [[Mars]])
