A control device (10) incorporated into a spacecraft (100) generates a target orbit in order for the spacecraft to navigate an approach to an uncooperative target object (200) in a plane F defined by: a first vector (V1) which is a vector that passes through the center of gravity (FP) of the uncooperative target object and is parallel to the longitudinal direction of the uncooperative target object, and which includes a vector component of a direction that will cause the spacecraft to approach the uncooperative target object; and a second vector V2 which is a vector in an imaging direction D1 of a captured image of the uncooperative target object.
