Nakano Note (Nakano wa Kangaeru noda) NK 2833 P/2014 W9 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 86 observations 2014 Oct. 25 to 2015 Feb. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.33 arc second. Epoch = 2015 Feb. 27.0 TT T = 2015 Feb. 15.70699 +/- 0.00031 (m.e.) TT Peri. = 167.77047 +/- 0.00024 Node = 21.28789 +/- 0.00019 (2000.0) Inc. = 10.63048 +/- 0.00001 q = 1.5874365 +/- 0.0000055 AU e = 0.8577487 +/- 0.0000207 a = 11.1593839 +/- 0.0001453 AU n' = 0.02643892 +/- 0.00000052 P = 37.279 +/- 0.0007281 years (+/- 0.27 day) The predicted orbit for the 2052 return is as follows: T = 2052 Apr. 28.11077 TT Epoch = 2052 Apr. 13.0 TT Peri. = 167.59751 e = 0.8585653 Node = 21.30291 (2000.0) a = 11.2547701 AU Inc. = 10.62543 n'= 0.02610352 q = 1.5918146 AU P = 37.758 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 141220 I89 0.4+ 0.6+ 150125 C51 0.1- 0.9+ 141025 G96 0.6+ 0.2- 141220 I89 0.1+ 0.5+ 150125 C51 0.0 0.7+ 141025 G96 0.2+ 0.2+ 141224 703 (0.3- 2.3+) 150128 F51 0.0 0.1- 141025 G96 0.2+ 0.4+ 141224 703 (0.2- 2.1+) 150128 F51 0.0 0.0 141025 G96 0.6- 0.4+ 141224 703 (2.8+ 2.0+) 150128 F51 0.0 0.1- 141122 F51 0.1+ 0.1- 141226 I89 0.1+ 0.3+ 150128 F51 0.1- 0.0 141122 F51 0.0 0.0 141226 I89 0.0 0.3+ 150130 F51 0.1+ 0.1- 141122 F51 0.1+ 0.1- 141230 703 0.4+ 0.8+ 150130 F51 0.0 0.1- 141123 W96 1.0+ 0.6- 141230 703 0.4+ 1.1+ 150130 F51 0.0 0.1- 141123 W96 0.8- 0.4+ 141230 703 0.1+ 0.9+ 150130 F51 0.0 0.1- 141123 291 0.8+ 1.6+ 141230 703 0.3- 1.3+ 150131 Q62 0.3+ 0.3+ 141123 291 0.2- 0.8+ 2015/ 150131 Q62 0.3+ 0.1+ 141123 291 0.1- 0.3+ 150108 F51 0.0 0.2- 150131 Q62 0.5+ 0.0 141123 H06 (2.9+ 3.5+) 150108 F51 0.0 0.1- 150214 703 0.1- 0.6+ 141123 H06 (3.2+ 3.4+) 150108 F51 0.0 0.1- 150214 703 (0.4- 2.9+) 141123 568 0.1+ 0.2- 150108 F51 0.0 0.1- 150214 703 1.7- 1.8+ 141123 568 0.0 0.1- 150120 H06 0.3+ 0.6+ 150214 703 0.2+ 1.2+ 141123 568 0.1- 0.1- 150120 H06 (0.9+ 2.0+) 150220 D95 1.8+ 0.5- 141124 291 0.1+ 0.6+ 150123 C51 0.1- 0.1+ 150220 D95 0.4- 0.7+ 141124 291 0.0 0.3+ 150123 C51 0.0 0.5+ 150220 D95 0.3+ 0.9+ 141124 291 0.5- 0.5+ 150123 C51 0.4- 0.1- 150221 215 0.7+ 0.2+ 141125 568 0.0 0.1- 150123 C51 0.1+ 0.4+ 150221 215 0.6+ 0.4+ 141125 568 0.1- 0.1- 150123 C51 0.6+ 0.7+ 150221 215 0.3+ 1.5+ 141125 568 0.0 0.1- 150123 C51 0.6- 0.3+ 150224 W88 0.3- 0.1- 141126 F51 0.1- 0.0 150124 C51 0.3+ 0.5+ 150224 W88 0.1+ 0.0 141126 F51 0.1- 0.1+ 150124 C51 0.4+ 0.7+ 150224 W88 0.1+ 0.0 141126 F51 0.1+ 0.0 150124 C51 0.2+ 0.3+ 150224 W88 0.1- 0.3+ 141126 F51 0.0 0.0 150124 C51 0.1- 0.5+ 150225 F51 0.1- 0.1- 141130 F51 0.0 0.1- 150124 C51 0.5+ 0.3- 150225 F51 0.0 0.1- 141130 F51 0.1- 0.1- 150124 C51 0.1+ 0.4+ 150225 F51 0.1- 0.1- 141130 F51 0.1- 0.1- 150124 C51 0.2+ 0.5+ 150225 F51 0.1- 0.2- 141220 I89 0.9+ 0.7+ 150124 C51 0.3+ 0.1+ ( ) -------- Rejected Obs.
