  In this paper it is reconciled how the metric in Minkowskian space-time gets
transformed from one coordinates system to another after successive Lorentz
transformations. And likewise this idea is generalized to achieve metric
transformation from one curved spacetime to another. The synergy between
different sources of masses manifests curved space-time perturbed and the
perturbed metric is assumed as point-to-point infinitesimal quasi Lorentz
transformation of the Minkowski metric. For two body system this model of
linear perturbation interactive gravity is tested for the unstable planetary
elliptical orbit and the precession of perihelion is revisited.
