Nakano Note (Nakano wa Kangaeru noda) NK 3162 P/2014 W4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 66 observations 2014 Oct. 25 to 2016 May 5. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.35 arc second. See the previous orbits in NK 3027 and NK 3136. Epoch = 2016 Jan. 13.0 TT T = 2015 Dec. 29.66565 +/- 0.01341 (m.e.) TT Peri. = 67.43305 +/- 0.00176 Node = 33.35278 +/- 0.00006 (2000.0) Inc. = 15.27440 +/- 0.00003 q = 4.2610643 +/- 0.0000203 AU e = 0.3531035 +/- 0.0000089 a = 6.5869334 +/- 0.0000146 AU n' = 0.05830142 +/- 0.00000019 P = 16.905 +/- 0.0000563 years The predicted orbit for the 2032 return is as follows: T = 2032 Nov. 25.83617 TT Epoch = 2032 Nov. 24.0 TT Peri. = 67.50298 e = 0.3544533 Node = 33.22710 (2000.0) a = 6.5963868 AU Inc. = 15.26881 n'= 0.05817614 q = 4.2582755 AU P = 16.942 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 141120 W96 0.5- 0.7- 151107 461 0.3- 0.3+ 141025 F51 0.4- 0.0 141120 W96 0.5+ 0.1+ 151107 461 0.5- 0.1+ 141025 F51 0.0 0.2- 141120 W96 0.4- 0.1+ 151107 461 0.3- 0.2+ 141025 F51 0.2+ 0.1+ 141120 695 0.1- 0.6- 151203 F51 0.2+ 0.0 141118 F51 0.1- 0.1- 141120 695 0.1- 0.1+ 151203 F51 0.2+ 0.0 141118 F51 0.1+ 0.1- 141120 695 0.1+ 0.1- 151203 F51 0.2+ 0.0 141118 F51 0.2+ 0.0 141211 F51 0.1- 0.1+ 151203 F51 0.2+ 0.1- 141118 F51 0.2+ 0.1- 141211 F51 0.2+ 0.3+ 151218 G45 1.2- 0.1- 141119 H01 0.1+ 0.3+ 141211 F51 0.0 0.2+ 151218 G45 0.2- 0.2- 141119 H01 0.0 0.3+ 141211 F51 0.2- 0.2+ 151218 G45 0.4- 0.1+ 141119 H01 0.1+ 0.3+ 2015/ 151218 G45 0.4- 0.2- 141119 H01 0.1+ 0.2+ 150213 461 0.1+ 0.3+ 151218 G45 0.5- 0.0 141119 695 0.7- 0.1- 150213 461 0.2- 0.4+ 151218 G45 1.2- 0.1- 141119 695 0.3+ 0.1+ 150213 461 0.2+ 0.3+ 151218 G45 0.3- 0.0 141119 568 0.2+ 0.1+ 150214 G45 0.7- 0.1- 151218 G45 0.9- 0.2- 141119 568 0.2+ 0.1+ 150214 G45 0.0 0.4+ 2016/ 141119 568 0.2+ 0.1+ 150214 G45 0.4+ 0.4+ 160328 H06 0.1+ 0.3+ 141119 Q62 0.5- 0.3+ 150214 G45 0.4- 0.0 160328 H06 0.1+ 0.2+ 141119 Q62 0.3- 0.1- 150214 G45 0.8- 0.6- 160328 H06 0.0 0.0 141119 Q62 0.1- 0.4- 151106 461 0.6- 0.1- 160429 215 0.7- 0.3- 141119 958 0.4- 0.5- 151106 461 0.4- 0.0 160505 215 0.3+ 0.1- 141119 958 0.7- 0.7- 151106 461 0.9- 0.1+ 160505 215 0.1+ 0.1- 141119 958 0.1- 0.6- 151107 461 0.4- 0.5+ 160505 215 0.1+ 0.2- ( ) -------- Rejected Obs.
