To see this, recall from Appendix C that the Newtonian orbit equation (d'u/dp?)+ u= M/L? has à = helion at p = 0. The hypotheses imply r> L»M SO this is close to the relativistic solution. To obtain a more refined approximation, we use ü in (M/L")(1 + e cos φ) as solution with peri- the relativistic correction term thus 代人 (d'u/dp?) + u = (M/L?) + 3Mz?.
