Bi-elliptic transfer orbit maneuver
Comparing bi-elliptic transfer orbit and the Hohmann transfer orbit. The latter can be more efficient when the target orbit is far larger than the initial orbit.
The dashed curve completes the ellipse but isn’t part of the orbit. The abrupt change in curvature is at the furthest point of the elliptical orbits is striking, but I believe the graph is correct. The bi-elliptical transfer orbit need not extend past the outer circle at all.
