Nakano Note (Nakano wa Kangaeru noda) NK 3486 P/2014 HU195 (Valdes-TOTAS)
The following improved orbital elements, by S. Nakano, are from 56 observations 2014 Apr. 24 to 2017 June 22. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. See the previous orbit in NK 3218 (= HICQ 2017). Epoch = 2015 May 18.0 TT T = 2015 May 18.02272 +/- 0.00180 (m.e.) TT Peri. = 145.07183 +/- 0.00017 Node = 115.78829 +/- 0.00007 (2000.0) Inc. = 5.82259 +/- 0.00002 q = 5.1211623 +/- 0.0000050 AU e = 0.7653038 +/- 0.0000060 a = 21.8203931 +/- 0.0005497 AU n' = 0.00966964 +/- 0.00000037 P = 101.928 +/- 0.0038438 years (+/- 1.40 days) The predicted orbit for the 2117 return is as follows: T = 2117 Sept.17.72484 TT Epoch = 2117 Aug. 31.0 TT Peri. = 145.22732 e = 0.7651298 Node = 115.72805 (2000.0) a = 21.7754067 AU Inc. = 5.82934 n'= 0.00969962 q = 5.1143948 AU P = 101.613 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 160706 Y28 0.1+ 0.1- 160808 F51 0.0 0.0 140424 W84 0.1- 0.1- 160706 Y28 0.0 0.0 160808 F51 0.0 0.1+ 140424 W84 0.1- 0.1+ 160706 H06 1.7- 1.0- 160808 F51 0.0 0.1- 140424 W84 0.1+ 0.1- 160706 H06 (2.2- 0.8-) 160808 F51 0.0 0.0 140424 W84 0.0 0.0 160706 H06 1.8- 0.9- 160808 F51 0.1+ 0.0 140424 W84 0.1+ 0.1- 160706 568 0.1+ 0.0 160808 F51 0.1+ 0.1+ 140425 W84 0.0 0.0 160706 568 0.1+ 0.0 160808 F51 0.0 0.0 140425 W84 0.1- 0.0 160706 568 0.1+ 0.0 160808 F51 0.0 0.1+ 140425 W84 0.1+ 0.1- 160706 568 0.1+ 0.0 160822 215 1.3- 0.5- 140425 W84 0.0 0.1- 160706 568 0.1+ 0.0 160822 215 1.2- 0.3- 140425 W84 0.1- 0.0 160706 568 0.1+ 0.1+ 160822 215 1.3- 0.1+ 2016/ 160707 568 0.3+ 0.0 161006 568 0.0 0.0 160705 J04 1.1- 0.4- 160707 568 0.3+ 0.0 161006 568 0.1+ 0.0 160705 J04 1.3- 0.3+ 160707 568 0.4+ 0.1+ 161006 568 0.2+ 0.1+ 160705 J04 0.5- 0.5+ 160716 G96 1.8- 0.3- 161029 568 0.0 0.1- 160705 J04 0.1+ 0.4+ 160716 G96 1.3- 0.3+ 161029 568 0.1+ 0.0 160706 C10 0.8- 0.8- 160716 G96 0.8- 0.4+ 2017/ 160706 Y28 0.0 0.0 160716 G96 1.8- 0.0 170622 568 0.0 0.0 160706 Y28 0.2- 0.1+ 160728 D29 1.7- 0.7- 170622 568 0.0 0.0 160706 C10 0.9- 1.2- 160728 D29 0.9- 0.3- 170622 568 0.0 0.0 ( ) -------- Rejected Obs.
