Dorogie druz'ya, poschital, chto nekrasivo otvechat' obshimi slovami. Vot neskol'ko cifr. Rezul'taty svereny s chislennoi model'yu dvizheniya planet, Luny i Solnca DE406/LE406 (Laboratoriya reaktivnogo dvizheniya SShA). Model' postroena s uchetom relyativistskih effektov i ispol'zovaniem "izotropnyh" koordinatnyh uslovii.
Interval prognoza sostavlyaet 7000 let.
Planeta Merkurii. Bol'shaya poluos':
minimal'noe znachenie - 0.3870970 astronomicheskih edinic,
maksimal'noe znachenie - 0.3871009 astronomicheskih edinic,
period izmeneniya korreliruet i s periodom obrasheniya Venery, i s periodom obrasheniya Zemli, i, konechno, s periodom obrasheniya Yupitera.
Planeta Merkurii. Argument perigeliya:
korotkoperiodicheskie neravenstva (44 dnya, 88 dnei) neveliki, poryadka 1 sekundy dugi, no na nih nakladyvaetsya znamenitoe v teorii dvizheniya Luny dolgoperiodicheskoe neravenstvo ot Venery, chto odin raz v 15 zemnyh let privodit k plavnym uvelicheniyam chislovogo znacheniya argumenta perigeliya orbity Merkuriya na velichinu do 28 uglovyh sekund v techenie odnogo zemnogo goda.
Vekovoe izmenenie chislovogo znacheniya argumenta perigeliya orbity Merkuriya legko vydelyaetsya i sostavlyaet v sisteme fiksirovannyh na epohu J2000.0 ekvatora i ekliptiki 10.4018 uglovyh sekund v god. (Teoreticheskii rezul'tat sera Saimona N'yukoma - 532 sekundy dugi v stoletie - poluchen dlya vrashayusheisya ekliptiki.)
Vse, o chem govoril uvazhaemyi Dmitrii, tol'ko podtverzhdaetsya etimi ciframi. Shag chislennogo integrirovaniya uravnenii dvizheniya v modeli, sozdannoi Laboratoriei reaktivnogo dvizheniya, sostavlyaet 0.08 zemnyh sutok! Esli ispol'zovat' slishkom bol'shoi shag integrirovaniya (bolee 1 sutok), to reshenie dlya Merkuriya i Luny stanovitsya neustoichivym.
S poklonom, Vadim.
