Nakano Note (Nakano wa Kangaeru noda) NK 3355 P/2017 D1 (Fuls)
The following improved orbital elements, by S. Nakano, are from 71 observations 2015 Sept. 8 to 2017 Mar. 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.50 arc second. Epoch = 2016 June 21.0 TT T = 2016 June 28.28363 +/- 0.00045 (m.e.) TT Peri. = 7.25494 +/- 0.00009 Node = 82.33548 +/- 0.00004 (2000.0) Inc. = 20.73246 +/- 0.00002 q = 2.6877906 +/- 0.0000011 AU e = 0.4403433 +/- 0.0000035 a = 4.8025706 +/- 0.0000063 AU n' = 0.09364691 +/- 0.00000018 P = 10.525 +/- 0.0000207 years The predicted orbit for the 2027 return is as follows: T = 2027 Jan. 31.06592 TT Epoch = 2027 Feb. 4.0 TT Peri. = 8.17618 e = 0.4378802 Node = 82.18177 (2000.0) a = 4.8202702 AU Inc. = 20.77146 n'= 0.09313159 q = 2.7095694 AU P = 10.583 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2015/ 160305 F51 0.0 0.2+ 170222 H06 0.0 0.2- 150908 F51 0.0 0.1- 160306 F51 0.1- 0.2- 170222 I52 0.6- 0.4- 150908 F51 0.4- 0.3+ 160306 F51 0.1- 0.2+ 170222 I52 0.2- 0.2- 150909 F51 0.1+ 0.0 160306 F51 0.2- 0.2+ 170222 I52 0.1+ 0.2- 150909 F51 0.0 0.1- 160306 F51 0.1- 0.2+ 170222 I52 0.4+ 0.4- 150909 F51 0.0 0.1- 161105 G96 0.8- 0.2+ 170222 I52 0.0 0.2+ 150909 F51 0.1- 0.1+ 161105 G96 1.9- 0.7+ 170222 I52 0.1+ 0.2- 151010 F51 0.1+ 0.0 161105 G96 0.8- 0.3+ 170222 I52 0.1- 0.0 151010 F51 0.1+ 0.1- 161105 G96 0.7- 0.5+ 170225 I52 0.4- 1.0- 151010 F51 0.2+ 0.1- 2017/ 170225 I52 1.1- 1.0- 151010 F51 0.2+ 0.2+ 170128 G96 0.3- 0.4- 170225 I52 0.6+ 1.6+ 151013 F51 0.1+ 0.0 170128 G96 1.1- 0.5+ 170227 D35 1.2+ 0.4+ 151013 F51 0.0 0.2- 170128 G96 0.1+ 0.0 170227 D35 (2.6+ 0.9+) 151013 F51 0.1+ 0.0 170128 G96 0.5- 0.6+ 170227 D35 0.6+ 0.7+ 151205 F51 0.1- 0.4- 170221 G96 0.4- 0.2- 170302 215 0.6- 1.4- 151205 F51 0.1+ 0.3- 170221 G96 0.5+ 0.0 170302 215 0.0 0.8- 151205 F51 0.2+ 0.1- 170221 G96 0.3+ 0.1- 170302 215 0.2+ 0.7+ 151205 F51 0.0 0.2- 170221 G96 0.6+ 0.0 170305 G96 0.7- 0.7- 2016/ 170221 G96 1.5+ 0.8- 170305 G96 0.7+ 0.7- 160103 F51 0.0 0.0 170221 G96 0.5+ 0.1- 170305 G96 0.6- 0.8- 160103 F51 0.0 0.1+ 170221 I52 0.5+ 0.3- 170305 G96 0.4- 0.9+ 160103 F51 0.0 0.0 170221 I52 0.8+ 0.3- 170307 G96 0.0 0.7- 160103 F51 0.1- 0.1+ 170221 I52 0.6+ 0.8+ 170307 G96 0.2+ 0.3- 160305 F51 0.2- 0.2+ 170221 G96 1.7- 0.2+ 170307 G96 1.0+ 0.1+ 160305 F51 0.1- 0.2+ 170222 H06 0.6- 0.4+ 170307 G96 0.7+ 0.1- ( ) -------- Rejected Obs.
