Chto
sobstvenno v etom sluchai interesno - eto to chto proishodit so vremenem,
i kak i kuda dvizhutsya fokal'nye tochki ellipticheskih orbit po otnosheniyu drug
k drugu, i kak menyayutsya radiusy ellipsov so vremenem.
Sobstvenno eto tozhe ne logichno ne zamechat' pri ob'yasnenii dvizheniya planet
po svoim opredelennym orbitam.
S moei tochki zreniya dolzhny byt'
kakie-to vliyaniya naprimer Solnca kotorye stabiliziruyut orbitu i priblizhayut
ee k krugloi, i est' naprimer, vliyanie drugih planet kotorye uvelichivayut ellips.
