Dopushena oshibka iliv opredelenii rasstoyaniya planety ot Solnca, ili v periode ee obrasheniya vokrug Solnca. Esli schitat', chto rasstoyanie do desyatoi planety 14,5 mlrd.
km, to period obrasheniya dolzhen sostavlyat' 954,244 goda. Esli schitat', chto period sostavlyaet 560 let, to rasstoyanie mezhdu Solncem i planetoi dolzhno sostavlyat' 10169907502
km (10,169 mlrd. km) S uvazheniem V.D. Krasnov E-mail: apeyron@kolomna.ru

Deistvitel'no, po gruboi prikidke period obrasheniya raven 97*SQR(97) = 955 let. S popravkoi na ekscentrisitet zemnoi orbity sovpadaet s vychisleniyami (1). Tak chto yavnaya oshibka. (2):
Tak i ponyatno, esli perigelii 36 AU, a afelii97AU, orbita yavno ne krugovaya. S bol'shim ekscintrisitetom 0.928. Tak natretii zakon Keplera priduman. Sravnivayutsya odinakovye
elementy orbit, tradicionno - bol'shie poluosi.

E.Griv , ispol'zuya teoriyu volnovyh dvizhenii, vyvodit zakon Ticiusa-Bode (Blegga- Richardsona) v vide a=r0*A**n, gde r0=0.21 a.e, A=1.73, n=1,2,... (Pluton ignoriruetsya)i obosnovyvaet
sushestvovanie planet na KRUGOVYH orbitah s radiusami 87 a.e., 151 a.e., 251, a.e. 462 a.e. i 783 a.e. (sm. materialy 197 simpoziuma IAU "Dynamics of Populations of Planetary
Systems". Eds Knesevich , A. Milani. 2005. )
V Trudah VIII s'ezda Astronomicheskogo obshestva N.I.Perov (GAISh MGU, iyun', 2005), rassmatrivaya model' proishozhdeniya Sedny, obosnovyvaet sushestvovanie planety s a=87 a.e.
s dolgotoi 209 gradusov (na iyul' 2005 g.), s sootnosheniem R/M bol'she, chem dlya Zemli v 6 raz.
Krome Sireni v oblasti 40-100 a.e. , veroyatno, budut obnaruzheny i drugie MALYE tela Solnechnoi sistemy.
