Nakano Note (Nakano wa Kangaeru noda) NK 3028 P/2015 GX (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 212 observations 2015 Apr. 8 to November 27. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.60 arc second. 2015 November observations show the residuals of -11" mainly for Declination from a recent orbit. See an orbit in NK 2986 (= HICQ 2015). Epoch = 2015 Sept.15.0 TT T = 2015 Aug. 26.66110 +/- 0.00076 (m.e.) TT Peri. = 108.95761 +/- 0.00034 Node = 235.51541 +/- 0.00005 (2000.0) Inc. = 90.25463 +/- 0.00003 q = 1.9717537 +/- 0.0000049 AU e = 0.8781840 +/- 0.0000076 a = 16.1863213 +/- 0.0000621 AU n' = 0.01513498 +/- 0.00000009 P = 65.121 +/- 0.0003746 years (+/- 0.14 day) The predicted orbit for the 2080 return is as follows: T = 2080 July 7.09889 TT Epoch = 2080 July 15.0 TT Peri. = 108.61181 e = 0.8799405 Node = 235.51549 (2000.0) a = 16.5340326 AU Inc. = 89.98629 n'= 0.01466006 q = 1.9850674 AU P = 67.231 years The following residuals in seconds of arc are from the above orbital elements:
