Nakano Note (Nakano wa Kangaeru noda) NK 4359 P/2020 T3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 80 observations 2020 Sept. 9 to 2021 Jan. 2. 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 an orbit in CBET 4872. Epoch = 2021 Jan. 26.0 TT T = 2021 Jan. 20.47207 +/- 0.00031 (m.e.) TT Peri. = 357.04418 +/- 0.00042 Node = 74.01927 +/- 0.00031 (2000.0) Inc. = 7.29598 +/- 0.00003 q = 1.4366151 +/- 0.0000042 AU e = 0.5915787 +/- 0.0000096 a = 3.5174833 +/- 0.0000830 AU n' = 0.14940186 +/- 0.00000529 P = 6.597 +/- 0.0002334 years (+/- 0.09 day) The predicted orbit for the 2027 return is as follows: T = 2027 Aug. 28.05847 TT Epoch = 2027 Aug. 23.0 TT Peri. = 357.13596 e = 0.5921562 Node = 73.96168 (2000.0) a = 3.5143772 AU Inc. = 7.29892 n'= 0.14959998 q = 1.4333170 AU P = 6.588 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2020/ 201014 711 0.4+ 0.2- 201020 F52 0.1+ 0.6+ 200909 F51 0.5- 0.1- 201014 F51 0.1- 0.2- 201020 F52 0.1- 0.4+ 200913 F52 0.1+ 0.3- 201014 F51 0.2- 0.0 201020 F52 0.2+ 0.3- 200913 F52 0.2+ 0.0 201014 F51 0.1- 0.0 201021 G96 1.1+ 1.0+ 200913 F52 0.1- 0.3+ 201014 F51 0.1+ 0.0 201021 G96 0.1+ 0.3+ 200913 F52 0.0 0.0 201014 F51 0.1+ 0.1+ 201021 G96 0.1+ 0.2+ 200913 F52 0.4+ 0.0 201014 F51 0.1- 0.1- 201021 G96 0.1+ 0.3+ 200924 G96 0.2- 0.3+ 201014 Z84 0.2+ 0.2+ 201022 F51 0.2+ 0.2+ 200924 G96 0.3- 0.4+ 201014 Z84 0.5+ 0.5- 201022 F51 0.0 0.0 200924 G96 0.3+ 0.2- 201014 Z84 0.4+ 0.3- 201022 F51 0.6+ 0.2+ 200924 G96 0.8+ 0.0 201015 711 0.5- 1.1- 201022 F51 0.1+ 0.2+ 201010 G96 0.0 0.5+ 201015 711 0.2- 0.5- 201105 F51 0.0 0.0 201010 G96 0.1+ 1.2+ 201015 711 0.2- 0.3- 201105 F51 0.0 0.1+ 201010 G96 0.3+ 0.2+ 201015 711 0.3- 0.1+ 201105 A77 0.6+ 1.5+ 201010 G96 0.3+ 0.1+ 201015 E10 0.2- 0.2+ 201105 A77 0.9+ 1.6+ 201010 F51 0.1- 0.2- 201015 E10 0.2+ 0.1+ 201105 A77 0.5- 0.0 201010 F51 0.1+ 0.3- 201015 E10 0.2- 0.1+ 201116 F51 0.2- 0.1- 201010 F51 0.1+ 0.1- 201015 E10 0.0 0.1+ 201116 F51 0.2- 0.1- 201010 F51 0.0 0.1- 201016 E10 0.0 0.2+ 201116 F51 0.3- 0.1- 201011 F51 0.1- 0.2- 201016 E10 0.3- 0.2+ 201219 H06 0.3+ 0.0 201011 F51 0.1- 0.1- 201016 E10 0.2- 0.1- 201219 H06 0.5+ 0.2- 201011 Q62 0.6- 0.1- 201016 E10 0.1- 0.0 201219 H06 0.7+ 0.0 201011 Q62 0.6- 0.2- 201018 L01 0.3+ 0.9+ 201219 H06 0.4+ 0.0 201013 J04 0.0 0.3+ 201018 L01 0.2+ 0.9+ 2021/ 201013 J04 0.0 0.0 201018 L01 0.4- 0.8+ 210102 H06 0.3+ 0.5- 201013 J04 0.2+ 0.1+ 201019 568 0.3- 0.3- 210102 H06 0.5+ 0.5- 201014 711 0.3+ 0.3- 201019 568 0.3- 0.3- 201014 711 0.3+ 0.4- 201019 568 0.3- 0.3- ( ) -------- Rejected Obs.
