Nakano Note (Nakano wa Kangaeru noda) NK 3232 P/2016 G1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 139 observations 2016 Mar. 12 to Aug. 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.61 arc second. There is an orbit in HICQ 2016. Epoch = 2017 Jan. 7.0 TT T = 2017 Jan. 26.26357 +/- 0.00396 (m.e.) TT Peri. = 111.30281 +/- 0.00089 Node = 204.07445 +/- 0.00030 (2000.0) Inc. = 10.96811 +/- 0.00017 q = 2.0404284 +/- 0.0000257 AU e = 0.2101174 +/- 0.0000129 a = 2.5832047 +/- 0.0000206 AU n' = 0.23739187 +/- 0.00000284 P = 4.152 +/- 0.0000496 years The predicted orbit for the 2021 return is as follows: T = 2021 Mar. 22.19174 TT Epoch = 2021 Mar. 7.0 TT Peri. = 111.21618 e = 0.2112649 Node = 204.03803 (2000.0) a = 2.5836442 AU Inc. = 10.96796 n'= 0.23733130 q = 2.0378109 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/ 160404 568 0.0 0.0 160507 G45 0.5- 0.3- 160312 G96 0.0 0.3+ 160404 568 0.0 0.1+ 160507 G45 1.5- 0.5+ 160312 G96 0.2+ 0.2+ 160405 568 0.1+ 0.1+ 160507 G45 1.2- 0.3+ 160312 G96 0.0 0.2- 160405 568 0.1+ 0.1+ 160507 G45 0.6- 0.1+ 160312 G96 0.0 0.2+ 160405 568 0.2+ 0.1+ 160507 246 0.0 0.6- 160313 G45 0.5+ 0.0 160406 568 0.2+ 0.1+ 160507 246 0.4- 1.7- 160313 G45 0.2+ 0.0 160406 568 0.1+ 0.1+ 160507 246 0.5- 0.5- 160313 G45 0.2+ 0.2- 160406 568 0.1+ 0.1+ 160507 246 0.4- 0.8+ 160313 G45 0.3- 0.2+ 160407 461 0.6+ 0.2+ 160507 246 0.8- 0.1+ 160313 G45 0.1- 0.1+ 160407 461 0.2- 0.7- 160507 246 0.5- 1.0- 160313 G45 0.3- 0.0 160407 461 0.1+ 0.1- 160509 G96 1.5- 0.5- 160313 G45 0.1- 0.5+ 160411 G45 1.2- 0.7- 160509 G96 0.7- 0.4- 160316 G45 0.1+ 0.4+ 160411 G45 0.3- 0.3- 160509 G96 0.5+ 0.3+ 160316 G45 0.1- 0.0 160411 G45 0.1+ 0.9- 160509 A71 0.1- 0.0 160316 G45 0.1- 0.0 160411 G45 0.6- 0.8- 160509 A71 0.6- 0.8- 160316 G45 (3.6+ 0.1-) 160411 G45 1.6- 0.4+ 160510 G45 0.9- 0.7- 160401 F51 0.2+ 0.2- 160413 J22 0.3- 0.1- 160510 G45 0.9- 0.5- 160401 F51 0.2+ 0.0 160413 J22 1.4- 0.2+ 160510 G45 0.7- 0.7- 160401 F51 0.0 0.1- 160413 J22 0.6- 0.7+ 160510 G45 1.0- 0.3- 160401 F51 0.0 0.3+ 160416 F51 0.1+ 0.0 160524 K25 1.8- 0.4- 160402 568 0.0 0.0 160416 F51 0.5+ 0.3+ 160524 K25 0.8+ 0.7- 160402 568 0.0 0.0 160416 F51 0.4+ 0.1- 160527 J22 0.8- 0.7+ 160402 568 0.0 0.0 160429 A71 1.5- 0.3+ 160527 J22 0.2- 0.3+ 160402 Q62 0.2- 0.4- 160429 A71 0.7- 0.6- 160528 J22 0.1+ 0.3+ 160402 Q62 0.4- 0.2- 160430 703 (2.8- 1.3-) 160529 461 0.1- 0.5+ 160402 Q62 0.4- 0.1+ 160430 703 1.8- 0.5- 160529 461 0.8+ 1.8+ 160402 K91 0.5- 0.0 160430 703 0.8- 0.7- 160530 K25 0.1- 0.7+ 160402 K91 0.3- 0.2- 160501 K02 0.4+ 0.3+ 160530 K25 0.3- 0.1+ 160402 K91 0.4- 0.2- 160501 K02 0.4- 0.4+ 160602 Q21 1.7+ 0.1+ 160402 K91 0.4- 0.2- 160503 G40 0.6- 0.5- 160602 Q21 (0.5- 2.5+) 160403 I93 0.5- 0.0 160503 G40 0.3- 0.1- 160603 J22 0.9- 0.1+ 160403 I93 0.7- 0.3- 160504 F51 0.3+ 0.1- 160603 J22 0.4- 0.6+ 160403 I93 0.9- 0.1- 160504 F51 0.3+ 0.0 160603 J22 0.7+ 0.5+ 160403 448 0.7- 0.1+ 160504 F51 0.5+ 0.0 160605 157 0.5+ 0.0 160403 448 0.7- 0.4- 160504 F51 0.5+ 0.3+ 160605 157 0.2+ 0.5- 160403 G96 1.3- 0.2- 160504 K25 1.3- 0.3- 160605 157 0.6+ 0.7- 160403 G96 1.0- 0.4- 160504 K25 0.2- 0.5- 160609 H45 0.5- 0.9- 160403 448 0.1+ 0.4+ 160505 215 0.9- 0.5- 160609 H45 0.4+ 0.9- 160403 G96 0.5- 0.2- 160505 215 1.2- 0.2- 160609 H45 0.4+ 0.6- 160403 568 0.1+ 0.1+ 160505 215 1.3- 0.3+ 160609 H45 0.4+ 0.8- 160403 568 0.1+ 0.1+ 160506 J22 0.1+ 0.3- 160609 H45 1.1+ 1.0- 160403 568 0.1+ 0.0 160506 J22 0.9+ 0.3- 160625 585 1.3+ 0.0 160404 461 0.1- 0.2+ 160506 J22 0.2+ 1.0+ 160625 585 0.2- 1.6+ 160404 461 0.0 0.2- 160506 G45 0.7- 0.5- 160625 585 0.4+ 1.2+ 160404 461 0.4+ 0.6- 160506 G45 1.0- 0.7- 160625 585 0.6+ 1.7+ 160404 850 1.7- 0.1+ 160506 G45 1.2- 0.5- 160625 585 0.8- 1.7+ 160404 850 1.5- 0.3- 160506 G45 0.6- 0.4- 160809 W96 (2.8+ 2.3+) 160404 568 0.0 0.1+ 160507 G45 1.6- 0.1+ 160809 W96 0.4+ 1.0- ( ) -------- Rejected Obs.
