http://www.loptics.com/articles/starshape/starshape.html WebFor a hypothetical orbital system (Sun + single planet) the Newtonian model and the General Relativity (GR) model produce different expressions for the gravitational effect of the Sun on the planet. This is well known. The ratio between the Newtonian and GR effects is expressed in different ways by different writers.
