Nakano Note (Nakano wa Kangaeru noda) NK 2297 P/2005 V1 (Bernardi)
The following improved orbital elements, by S. Nakano, are from 43 observations 2005 Nov. 1 to 2007 June 15. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.17 arc second. See the previous orbits in NK 1353 and NK 1471. Epoch = 2005 Aug. 18.0 TT T = 2005 Aug. 12.56681 +/- 0.00041 (m.e.) TT Peri. = 357.31610 +/- 0.00018 Node = 129.73880 +/- 0.00004 (2000.0) Inc. = 15.62197 +/- 0.00001 q = 2.3450763 +/- 0.0000037 AU e = 0.4785748 +/- 0.0000009 a = 4.4974354 +/- 0.0000024 AU n' = 0.10333720 +/- 0.00000008 P = 9.538 +/- 0.0000076 years The predicted orbit for the 2015 return is as follows: T = 2015 Apr. 27.43778 TT Epoch = 2015 Apr. 8.0 TT Peri. = 0.43871 e = 0.4701435 Node = 127.65533 (2000.0) a = 4.5673993 AU Inc. = 16.10098 n'= 0.10097192 q = 2.4200663 AU P = 9.761 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2005/ 051108 204 0.5+ 0.1+ 2006/ 051101 568 0.0 0.0 051111 568 0.1+ 0.0 060402 204 0.0 0.0 051101 568 0.0 0.0 051111 568 0.1+ 0.0 060402 204 0.3+ 0.3- 051101 568 0.1+ 0.1- 051111 568 0.2+ 0.0 060428 568 0.1- 0.1+ 051101 568 0.1+ 0.1- 051112 204 0.3- 0.3- 060428 568 0.0 0.1+ 051102 568 0.1- 0.1- 051113 568 0.1+ 0.1- 060726 568 0.0 0.1- 051102 568 0.2- 0.0 051113 568 0.1+ 0.0 060726 568 0.0 0.0 051102 568 0.1- 0.1- 051113 568 0.2+ 0.1- 2007/ 051102 568 0.1- 0.0 051113 568 0.1+ 0.0 070224 568 0.0 0.1+ 051103 568 0.3- 0.2+ 051113 568 0.0 0.1- 070224 568 0.1+ 0.1+ 051103 568 0.3- 0.2+ 051113 568 0.1+ 0.1- 070224 568 0.2- 0.3+ 051103 568 0.0 0.1+ 051201 204 1.0- 0.0 070224 568 0.0 0.1- 051104 568 0.1- 0.0 051201 204 0.2- 0.0 070615 568 0.0 0.2- 051104 568 0.1+ 0.1- 051229 568 0.1- 0.1+ 070615 568 0.0 0.2- 051104 568 0.0 0.1- 051229 568 0.1- 0.0 051104 568 0.2+ 0.1- 051229 568 0.0 0.0 ( ) -------- Rejected Obs.
