Nakano Note (Nakano wa Kangaeru noda) NK 2963 P/2014 F3 (Sheppard-Trujillo)
The following improved orbital elements, by S. Nakano, are from 15 observations 2014 Mar. 26 to 2015 Apr. 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.49 arc second. Epoch = 2021 May 26.0 TT T = 2021 May 21.51073 +/- 1.62421 (m.e.) TT Peri. = 3.59645 +/- 0.01713 Node = 326.74789 +/- 0.00519 (2000.0) Inc. = 6.60047 +/- 0.00026 q = 5.6929083 +/- 0.0025934 AU e = 0.6315219 +/- 0.0005986 a = 15.4497877 +/- 0.0017442 AU n' = 0.01623007 +/- 0.00000249 P = 60.727 +/- 0.0104878 years (+/- 3.83 days) The predicted orbit for the 2075 return is as follows: T = 2075 Sept. 2.73743 TT Epoch = 2075 Sept.20.0 TT Peri. = 4.87912 e = 0.6021698 Node = 325.68766 (2000.0) a = 14.2946459 AU Inc. = 6.53399 n'= 0.01823660 q = 5.6868413 AU P = 54.046 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 140523 304 0.4+ 0.6+ 150321 304 0.0 0.1+ 140326 807 0.1- 0.7- 140524 Q62 0.7- 1.2- 150321 304 0.1- 0.1+ 140326 807 0.0 0.4- 140524 Q62 0.7- 0.9- 150418 304 0.3+ 0.2- 140328 807 0.4- 0.2- 140627 568 0.9- 0.2+ 150418 304 0.1+ 0.4- 140522 304 0.4+ 0.1+ 2015/ 150419 304 0.1+ 0.1- 140523 304 0.7+ 0.7+ 150321 304 0.5- 0.3+ ( ) -------- Rejected Obs.
