Nakano Note (Nakano wa Kangaeru noda) NK 2601 P/2013 P4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 70 observations 2013 Aug. 15 to Dec. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.52 arc second. Epoch = 2014 Aug. 11.0 TT T = 2014 Aug. 12.49268 +/- 0.44863 (m.e.) TT Peri. = 113.56856 +/- 0.04612 Node = 256.61605 +/- 0.00464 (2000.0) Inc. = 4.26447 +/- 0.00004 q = 5.9666609 +/- 0.0009905 AU e = 0.5960561 +/- 0.0002809 a = 14.7710149 +/- 0.0007149 AU n' = 0.01736155 +/- 0.00000126 P = 56.770 +/- 0.0041216 years (+/- 1.51 days) The predicted orbit for the 2071 return is as follows: T = 2071 Feb. 7.38742 TT Epoch = 2071 Feb. 13.0 TT Peri. = 114.32558 e = 0.6111138 Node = 255.77334 (2000.0) a = 15.3282205 AU Inc. = 4.24854 n'= 0.01642353 q = 5.9609340 AU P = 60.012 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2013/ 130826 E10 0.0 0.3- 130905 A71 0.7- 0.3- 130815 F51 0.0 0.1+ 130826 E10 0.1+ 0.1+ 130905 A71 0.3- 0.3- 130815 F51 0.1- 0.1+ 130826 E10 0.2+ 0.2+ 130909 A71 0.9+ 0.2- 130815 F51 0.1+ 0.1+ 130826 E10 0.3+ 0.1+ 130909 A71 0.1+ 0.6- 130815 F51 0.0 0.2+ 130827 Q62 0.7+ 0.2- 130925 E07 0.1+ 0.3- 130816 568 0.1- 0.1+ 130827 Q62 0.2+ 0.2- 130925 E07 0.4+ 0.5- 130816 568 0.1- 0.1+ 130827 Q62 0.1- 0.1+ 130927 F51 0.1+ 0.5+ 130816 568 0.1- 0.1+ 130828 W96 0.4- 0.0 130927 F51 0.1- 0.2+ 130817 Q62 1.2+ 0.4- 130828 W96 0.4- 1.0- 130927 F51 0.3+ 0.2+ 130817 Q62 1.4+ 0.6- 130831 474 0.1+ 0.0 130927 F51 0.1+ 0.0 130817 Q62 1.8+ 0.6- 130831 474 0.3- 0.5+ 131008 C32 1.6- 0.7+ 130819 807 0.1+ 0.9- 130831 474 0.1+ 0.2+ 131008 C32 1.4- 0.7+ 130819 807 0.2+ 0.9- 130902 G96 0.0 0.7- 131008 C32 0.7- 0.9+ 130826 H21 0.2+ 0.3- 130902 G96 0.5- 0.6- 131008 C32 0.9- 0.8+ 130826 H21 0.2- 0.4- 130902 G96 0.3- 0.9- 131012 G96 0.5+ 0.1- 130826 H21 0.4- 0.5- 130902 G96 0.6- 0.4- 131012 G96 0.1- 0.3- 130826 H21 0.1+ 0.9- 130902 Q62 0.0 0.2- 131012 G96 0.2+ 0.4- 130826 H36 0.8- 0.3- 130902 Q62 0.0 0.1- 131012 G96 0.4+ 1.0- 130826 H36 0.1+ 0.5- 130902 Q62 0.1- 0.0 131130 Q62 0.6- 0.6- 130826 H36 0.9- 1.0+ 130904 215 1.0- 1.6- 131130 Q62 0.1- 0.4- 130826 Q62 0.2- 0.3- 130904 215 0.1+ 0.1+ 131130 Q62 0.1+ 0.4- 130826 Q62 0.1- 0.2- 130904 215 0.2- 0.4- 131201 130 0.3+ 0.2- 130826 Q62 0.0 0.2- 130904 C10 0.8+ 0.9- 131201 130 1.1+ 0.3- 130826 E10 0.2+ 0.2- 130904 C10 0.1+ 0.6- ( ) -------- Rejected Obs.
