On a background of reference stars, the binary components move in non-rectilinear paths, which are the resultant of the uniform rectilinear motion of the center of mass and the orbital motion of the individual components.

It is one more proof of the reliability of the law of gravitation that paths, past and future, of the planets can thus be predicted more precisely than when the perturbations are neglected.
