Nakano Note (Nakano wa Kangaeru noda) NK 4853 P/2016 G1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 142 observations 2016 Mar. 12 to Sept. 26. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.58 arc second. See the previous orbit in NK 3232 (= HICQ 2017) which orbit gives T = 2025 May 16.0936 TT. Epoch = 2017 Jan. 7.0 TT T = 2017 Jan. 26.24605 +/- 0.00181 (m.e.) TT Peri. = 111.30359 +/- 0.00084 Node = 204.07370 +/- 0.00016 (2000.0) Inc. = 10.96767 +/- 0.00009 q = 2.0403294 +/- 0.0000196 AU e = 0.2101546 +/- 0.0000112 a = 2.5832009 +/- 0.0000442 AU n' = 0.23739240 +/- 0.00000609 P = 4.152 +/- 0.0001065 years (+/- 0.04 day) The 2021 return was not able to be recovered. The predicted orbit for the 2025 return is as follows: T = 2025 May 16.06961 TT Epoch = 2025 May 5.0 TT Peri. = 111.08926 e = 0.2100295 Node = 204.01026 (2000.0) a = 2.5837489 AU Inc. = 10.96962 n'= 0.23731687 q = 2.0410854 AU P = 4.153 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2016/ 160405 568 0.1+ 0.1+ 160507 G45 1.3- 0.2+ 160312 G96 0.4+ 0.2+ 160405 568 0.1+ 0.1+ 160507 G45 0.7- 0.1+ 160312 G96 0.6+ 0.0 160405 568 0.2+ 0.1+ 160507 246 0.1- 0.6- 160312 G96 0.5+ 0.3- 160406 568 0.2+ 0.1+ 160507 246 0.5- 1.7- 160312 G96 0.4+ 0.1+ 160406 568 0.1+ 0.1+ 160507 246 0.6- 0.5- 160313 G45 0.9+ 0.1- 160406 568 0.1+ 0.1+ 160507 246 0.5- 0.7+ 160313 G45 0.6+ 0.1- 160407 461 0.6+ 0.2+ 160507 246 1.0- 0.0 160313 G45 0.6+ 0.3- 160407 461 0.2- 0.7- 160507 246 0.7- 1.1- 160313 G45 0.1+ 0.1+ 160407 461 0.1+ 0.0 160509 G96 1.6- 0.5- 160313 G45 0.3+ 0.0 160411 G45 1.2- 0.7- 160509 G96 0.9- 0.4- 160313 G45 0.1+ 0.2- 160411 G45 0.3- 0.2- 160509 G96 0.4+ 0.3+ 160313 G45 0.3+ 0.4+ 160411 G45 0.0 0.9- 160509 A71 0.2- 0.0 160316 G45 0.5+ 0.3+ 160411 G45 0.7- 0.7- 160509 A71 0.7- 0.8- 160316 G45 0.3+ 0.1- 160411 G45 1.6- 0.4+ 160510 G45 1.1- 0.7- 160316 G45 0.3+ 0.1- 160413 J22 0.4- 0.0 160510 G45 1.0- 0.5- 160316 G45 (3.9+ 0.2-) 160413 J22 1.5- 0.3+ 160510 G45 0.9- 0.7- 160401 F51 0.3+ 0.2- 160413 J22 0.7- 0.7+ 160510 G45 1.1- 0.3- 160401 F51 0.3+ 0.0 160416 F51 0.0 0.1+ 160524 K25 1.8- 0.6- 160401 F51 0.1+ 0.1- 160416 F51 0.3+ 0.3+ 160524 K25 0.8+ 0.8- 160401 F51 0.0 0.4+ 160416 F51 0.3+ 0.1- 160527 J22 0.8- 0.5+ 160402 568 0.0 0.0 160429 A71 1.6- 0.3+ 160527 J22 0.1- 0.2+ 160402 568 0.0 0.0 160429 A71 0.9- 0.6- 160528 J22 0.2+ 0.2+ 160402 568 0.1+ 0.0 160430 703 (3.0- 1.3-) 160529 461 0.0 0.3+ 160402 Q62 0.1- 0.4- 160430 703 (2.0- 0.4-) 160529 461 1.0+ 1.6+ 160402 Q62 0.3- 0.2- 160430 703 0.9- 0.7- 160530 K25 0.0 0.5+ 160402 Q62 0.4- 0.1+ 160501 K02 0.2+ 0.3+ 160530 K25 0.2- 0.2- 160402 K91 0.5- 0.0 160501 K02 0.5- 0.4+ 160602 Q21 1.8+ 0.1- 160402 K91 0.3- 0.2- 160503 G40 0.8- 0.5- 160602 Q21 (0.3- 2.2+) 160402 K91 0.3- 0.2- 160503 G40 0.5- 0.1- 160603 J22 0.7- 0.2- 160402 K91 0.4- 0.2- 160504 F51 0.1+ 0.1- 160603 J22 0.2- 0.3+ 160403 I93 0.4- 0.0 160504 F51 0.1+ 0.0 160603 J22 0.9+ 0.2+ 160403 I93 0.6- 0.3- 160504 F51 0.3+ 0.0 160605 157 0.7+ 0.3- 160403 I93 0.8- 0.1- 160504 F51 0.3+ 0.3+ 160605 157 0.4+ 0.8- 160403 448 0.6- 0.1+ 160504 Q62 0.6- 0.1- 160605 157 0.8+ 0.9- 160403 448 0.6- 0.4- 160504 Q62 0.4- 0.2+ 160609 H45 0.3- 1.2- 160403 G96 1.3- 0.2- 160504 K25 1.5- 0.3- 160609 H45 0.6+ 1.2- 160403 G96 1.0- 0.4- 160504 K25 0.4- 0.5- 160609 H45 0.6+ 0.9- 160403 448 0.2+ 0.4+ 160505 215 1.1- 0.5- 160609 H45 0.7+ 1.0- 160403 G96 0.5- 0.1- 160505 215 1.3- 0.2- 160609 H45 1.3+ 1.3- 160403 568 0.1+ 0.1+ 160505 215 1.5- 0.3+ 160625 585 1.6+ 0.3- 160403 568 0.1+ 0.1+ 160506 J22 0.0 0.3- 160625 585 0.1+ 1.4+ 160403 568 0.1+ 0.0 160506 J22 0.8+ 0.3- 160625 585 0.7+ 0.9+ 160404 461 0.1- 0.2+ 160506 J22 0.0 1.0+ 160625 585 0.9+ 1.4+ 160404 461 0.0 0.2- 160506 G45 0.8- 0.5- 160625 585 0.6- 1.4+ 160404 461 0.5+ 0.6- 160506 G45 1.2- 0.7- 160809 W96 (2.0+ 2.4+) 160404 850 1.7- 0.1+ 160506 G45 1.3- 0.5- 160809 W96 0.5- 0.8- 160404 850 1.4- 0.3- 160506 G45 0.7- 0.4- 160926 568 1.5+ 1.8+ 160404 568 0.0 0.1+ 160507 G45 1.8- 0.1+ 160926 568 1.5+ 1.5+ 160404 568 0.0 0.1+ 160507 G45 0.6- 0.3- 160926 568 (2.0+ 2.3+) 160404 568 0.0 0.1+ 160507 G45 1.7- 0.4+ ( ) -------- Rejected Obs.
