... The laws of general relativity modify the way objects move near large masses (relative to their Newtonian motion). For example, Mercury’s orbit close to the sun is changed so that its perihelion ‘precesses’ with time. The precession of Mercury’s orbit due to general relativity is only 43 arc seconds ...
