Fundamental planetary science problem 2.5 the most easily observable effect of general relativity is the precession of orbits because it is nil in the newtonian two-body approximation. the first-order (weak-field) general relativistic corrections to newtonian grav- ity imply a precession of the periapse of orbit of a small body (m2 < < mı) about a primary of mass mı at the rate as/(1- where c is the speed of the light. calculate the general relativistic precession of the periapse of the following object. a) mercury b) earth c) io's orbit around jupiter, quote your answer to arcseconds per year.
