What Is the Hohmann Two-Burn Orbital Transfer Trajectory & Delta-V Calculator?
Walter Hohmann demonstrated that an elliptical transfer orbit tangent to both initial and final circular orbits minimizes fuel consumption.
It uses two tangential burns: the first raises the apoapsis to target altitude, and the second circularizes the orbit.
