Uvazhaemyi kollega, dorogie druz'ya.
Vashi voprosy ko mne ochen' pravil'nye, ibo ne dogovoril, perestavil hody. V teoreticheskih vykladkah pishut ob argumente perigeliya Merkuriya, imenno v izmeneniyah etogo parametra orbity Merkuriya proyavlyaetsya relyativistskii effekt. No vse uchenye 19-go i 20-go vekov privodyat "nablyudaemoe" znachenie precessii dolgoty perigeliya - okolo 5600 sekund dugi v stoletie v sisteme mgnovennoi ekliptiki i podvizhnogo ekvatora.
Dolgota perigeliya yavlyaetsya summoi dvuh uglov - dolgoty voshodyashego uzla i argumenta perigeliya orbity. Rezul'taty vychisleniya dayut vekovoe izmenenie argumenta perigeliya Merkuriya okolo +10 sekund v god i vekovoe izmenenie dolgoty voshodyashego uzla okolo -5 sekund v god. Summa - pochti plyus 6 uglovyh sekund v god dlya skorosti izmeneniya dolgoty perigeliya v inercial'noi sisteme otscheta - ekliptika i ekvator fiksirovany na epohu 2000 goda.
Rezul'tat N'yukoma 532 uglovyh sekundy v stoletie - eto teoreticheskii rezul'tat dlya skorosti izmeneniya dolgoty perigeliya, uchityvayushii tol'ko gravitacionnoe vliyanie planet.
Model' dvizheniya planet Solnechnoi sistemy, poluchennaya na osnove obrabotki bolee chem 1 milliona nazemnyh i kosmicheskih nablyudenii i rekomendovannaya Mezhdunarodnym astronomicheskim soyuzom, sozdana i podderzhivaetsya na stranichke Laboratorii reaktivnogo dvizheniya SShA.
