An orbital maneuver to transfer between two circular orbits consisting of one burn to enter the transfer orbit and one to circularize in the final orbit.

In orbital mechanics, the Hohmann transfer orbit is an elliptical orbit used to transfer between two circular orbits of different radii in the same plane. The orbital maneuver to perform the Hohmann transfer uses two engine impulses: one to move a spacecraft onto the transfer orbit and a second to move off it.
