Nakano Note (Nakano wa Kangaeru noda) NK 3146 P/2015 GX (PANSTARRS)
The following improved orbital elements, by T. Kobayashi, are from 285 observations 2015 Apr. 8 to 2016 Feb. 28. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.53 arc second. See the previous orbits in NK 2986 (= HICQ 2015), NK 3028 and NK 3055. Epoch = 2015 Sept.15.0 TT T = 2015 Aug. 26.66174 +/- 0.00013 (m.e.) TT Peri. = 108.95782 +/- 0.00006 Node = 235.51552 +/- 0.00001 (2000.0) Inc. = 90.25452 +/- 0.00001 q = 1.9717554 +/- 0.0000008 AU e = 0.8782017 +/- 0.0000017 a = 16.1886905 +/- 0.0002212 AU n' = 0.01513166 +/- 0.00000031 P = 65.135 +/- 0.0013347 years (+/- 0.49 day) The predicted orbit for the 2080 return is as follows: T = 2080 July 12.28686 TT Epoch = 2080 July 15.0 TT Peri. = 108.61441 e = 0.8799463 Node = 235.51607 (2000.0) a = 16.5340390 AU Inc. = 89.98790 n'= 0.01466006 q = 1.9849717 AU P = 67.231 years The following residuals in seconds of arc are from the above orbital elements:
