Nakano Note (Nakano wa Kangaeru noda) NK 3335 P/2016 Q4 (Kowalski)
The following improved orbital elements, by S. Nakano, are from 78 observations 2016 July 11 to Nov. 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.68 arc second. Epoch = 2018 Feb. 11.0 TT T = 2018 Jan. 26.92326 +/- 0.49217 (m.e.) TT Peri. = 99.41235 +/- 0.04046 Node = 271.30508 +/- 0.00594 (2000.0) Inc. = 7.25677 +/- 0.00036 q = 7.0855675 +/- 0.0012588 AU e = 0.5786373 +/- 0.0002690 a = 16.8158386 +/- 0.0006628 AU n' = 0.01429309 +/- 0.00000085 P = 68.957 +/- 0.0040768 years (+/- 1.49 days) The predicted orbit for the 2087 return is as follows: T = 2087 Sept.12.46890 TT Epoch = 2087 Aug. 28.0 TT Peri. = 99.52110 e = 0.5801421 Node = 271.23047 (2000.0) a = 16.9112321 AU Inc. = 7.25218 n'= 0.01417233 q = 7.1003152 AU P = 69.545 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2016/ 160831 G96 0.6- 0.3- 160901 104 1.3+ 0.2+ 160711 F51 0.4+ 0.0 160831 U69 (3.6- 2.1-) 160901 585 0.2+ 0.6+ 160711 F51 0.4- 0.1+ 160831 U69 (3.8- 2.4-) 160901 585 0.6+ 0.1- 160803 F51 0.2+ 0.3- 160831 O75 0.8+ 1.0+ 160901 585 1.1- 0.9+ 160803 F51 0.4- 0.3- 160831 O75 0.2+ 0.9+ 160901 585 1.2+ 0.7+ 160803 F51 0.2+ 0.0 160831 C43 (2.3+ 0.7-) 160901 585 1.0+ 0.9- 160830 G96 1.5- 0.7- 160831 215 0.9- 0.5- 160901 461 0.9+ 0.6+ 160830 G96 1.1- 0.5- 160831 C43 1.2+ 0.1- 160901 461 0.5+ 0.3+ 160830 G96 (2.4- 0.4+) 160831 215 1.1- 0.5+ 160901 104 0.1- 0.5+ 160830 G96 0.8- 0.3- 160831 215 1.0- 1.7+ 160901 461 0.4+ 0.6+ 160830 G96 1.4- 0.0 160831 246 0.2+ 0.2- 160901 104 0.3- 0.4+ 160830 G96 1.2- 0.1+ 160831 246 1.0+ 0.2- 160901 104 0.4- 0.2+ 160830 G96 0.9- 0.7+ 160831 A71 0.4+ 0.2+ 160901 104 0.4- 0.6+ 160830 G96 0.7- 0.5+ 160831 461 1.0+ 0.9+ 160904 349 0.5+ 0.5+ 160830 C43 (2.4- 2.2+) 160831 461 0.1- 0.5+ 160904 Q62 0.1+ 0.4+ 160830 C43 (0.7- 5.1+) 160831 C10 0.4- 0.8- 160904 Q62 0.2+ 0.0 160830 J95 0.0 0.3- 160831 461 0.4- 0.1- 160904 349 0.0 0.1- 160830 A71 0.6+ 0.0 160831 A71 0.3- 0.0 160906 J22 0.0 1.0+ 160830 246 0.3- 0.9- 160831 C47 0.3- 0.1- 160906 J22 0.2- 0.8+ 160830 246 0.1- 1.7- 160831 C10 1.1- 0.4- 160924 A71 0.2+ 0.3- 160830 J95 0.7- 0.4- 160831 C47 0.3+ 0.1+ 160924 A71 0.0 0.3- 160830 246 0.8- 0.2- 160831 C43 (2.5+ 2.1-) 160927 J22 (1.6- 3.1-) 160830 J95 0.3- 0.3+ 160831 C10 0.7- 0.3+ 160927 J22 0.0 1.6- 160830 A71 0.3- 0.5+ 160831 106 0.1- 0.5- 160927 J22 1.9+ 0.4- 160830 C43 0.1- 1.3+ 160901 K38 0.9+ 0.0 161020 A77 1.7- 0.3+ 160830 I89 (2.8- 0.2-) 160901 106 1.1+ 0.6- 161020 A77 0.3+ 0.7- 160830 I89 (3.4- 0.2-) 160901 106 1.5+ 0.2- 161020 A77 0.4+ 0.3+ 160831 G96 0.4- 0.1+ 160901 K38 0.8+ 0.4- 161119 G40 0.7+ 0.6- 160831 G96 0.1+ 0.1+ 160901 G40 1.3- 0.4+ 161119 G40 0.3- 0.1- 160831 G96 0.8+ 0.7+ 160901 G40 1.0+ 1.3- ( ) -------- Rejected Obs.
