Nakano Note (Nakano wa Kangaeru noda) NK 4335 P/2018 P5 (PANSTARRS)
The following improved orbital elements, by T. Kobayashi, are from 81 observations 2018 June 16 to 2020 Feb. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.43 arc second. See the previous orbits in HICQ 2019 and NK 3902 (= HICQ 2020). Epoch = 2019 Mar. 18.0 TT T = 2019 Feb. 26.21986 +/- 0.00832 (m.e.) TT Peri. = 131.63443 +/- 0.00104 Node = 216.24149 +/- 0.00019 (2000.0) Inc. = 7.25683 +/- 0.00002 q = 4.5758872 +/- 0.0000089 AU e = 0.6409602 +/- 0.0000111 a = 12.7447925 +/- 0.0003945 AU n' = 0.02166232 +/- 0.00000101 P = 45.499 +/- 0.0021108 years (+/- 0.77 day) The predicted orbit for the 2064 return by S. Nakano from the above orbit is as follows: T = 2064 Oct. 14.81742 TT Epoch = 2064 Oct. 7.0 TT Peri. = 131.86687 e = 0.6421984 Node = 216.14825 (2000.0) a = 12.7591782 AU Inc. = 7.27003 n'= 0.02162569 q = 4.5652549 AU P = 45.576 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2018/ 180816 L01 0.4- 0.4+ 190710 G96 0.4- 0.2+ 180616 F51 0.0 0.0 180816 L01 0.4- 0.3- 190826 G37 0.1+ 0.1- 180616 F51 0.2+ 0.0 180816 104 0.4+ 0.3+ 190826 G37 0.1+ 0.1- 180623 F51 0.2+ 0.0 180817 104 0.9+ 0.8+ 190826 G37 0.1+ 0.1- 180623 F51 0.3+ 0.0 180817 104 0.3+ 0.6- 190826 G37 0.2+ 0.1- 180623 F51 0.3+ 0.0 180817 K88 0.0 0.0 190826 G37 0.1+ 0.2- 180623 F51 0.1+ 0.1- 180817 K88 0.1- 0.2+ 190830 G37 0.4+ 0.0 180713 F51 0.1+ 0.2+ 180818 F51 0.0 0.0 190830 G37 0.3+ 0.0 180713 F51 0.2+ 0.0 180818 F51 0.0 0.1- 190830 G37 0.4+ 0.0 180713 F51 0.0 0.1- 180818 F51 0.1+ 0.0 190830 G37 0.4+ 0.1- 180713 F51 0.1- 0.0 180818 F51 0.2+ 0.1+ 190923 H06 0.3+ 0.1- 180811 F51 0.1- 0.0 180905 A71 0.4- 0.2- 190923 H06 0.4+ 0.3- 180811 F51 0.1- 0.1+ 180905 A71 0.3- 0.8- 191006 F52 0.1+ 0.1+ 180811 F51 0.0 0.0 180905 215 0.4- 1.0- 191006 F52 0.1- 0.0 180811 F51 0.1+ 0.1- 180905 215 0.4- 1.0- 191006 F52 0.3- 0.1- 180812 568 0.2+ 0.0 180905 215 0.3- 1.1- 191024 F51 0.1+ 0.0 180812 568 0.0 0.0 180907 G96 0.5+ 0.5+ 191024 F51 0.1+ 0.1- 180812 568 0.1+ 0.0 180907 G96 0.2+ 0.1- 191024 F51 0.2+ 0.0 180815 F65 0.2- 0.1- 180907 G96 0.0 0.3+ 191024 F51 0.1+ 0.1- 180815 F65 0.9- 0.6- 180907 G96 0.1- 0.2- 191025 F51 0.1+ 0.1- 180815 F65 1.0- 0.6- 180908 K77 0.6+ 1.8+ 191025 F51 0.1+ 0.1- 180815 F65 0.6- 0.1- 180908 K77 1.9+ 1.8+ 191025 F51 0.0 0.0 180816 807 0.1- 0.2- 181008 461 0.1- 0.7+ 191025 F51 0.1- 0.1- 180816 807 0.0 0.2- 181008 461 0.5- 0.3+ 2020/ 180816 807 0.2- 0.2- 2019/ 200203 G96 0.6- 0.5+ 180816 Q62 0.1+ 0.3+ 190710 G96 0.0 0.3- 200203 G96 0.1+ 0.1+ 180816 Q62 0.3- 0.3+ 190710 G96 1.0- 0.6+ 200203 G96 0.1+ 0.5+ 180816 Q62 0.3- 0.5+ 190710 G96 0.6- 0.5- 200203 G96 0.9- 0.6+ ( ) -------- Rejected Obs.
