Nakano Note (Nakano wa Kangaeru noda) NK 3706 361P/Spacewatch
The following improved orbital elements, by S. Nakano, are from 223 observations 2006 to 2018. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.57 arc second. Residuals on 2018 October observations were +38" for Right Ascension and -4" for Declination from an orbit in NK 3443 (= HICQ 2018). Epoch = 2018 July 21.0 TT T = 2018 July 2.49759 +/- 0.00134 (m.e.) TT Peri. = 219.21172 +/- 0.00030 Node = 203.27722 +/- 0.00007 (2000.0) Inc. = 13.88232 +/- 0.00004 q = 2.7802892 +/- 0.0000019 AU e = 0.4378496 +/- 0.0000004 a = 4.9458104 +/- 0.0000049 AU n' = 0.08960823 +/- 0.00000013 P = 10.999 +/- 0.0000162 years T = 2007 July 2.65166 TT Epoch = 2007 June 29.0 TT Peri. = 219.21820 e = 0.4366080 Node = 203.43868 (2000.0) a = 4.9454053 AU Inc. = 13.87569 n'= 0.08961924 q = 2.7862020 AU P = 10.998 years The predicted orbit for the 2029 return is as follows: T = 2029 June 21.93688 TT Epoch = 2029 July 3.0 TT Peri. = 219.14293 e = 0.4385085 Node = 203.15342 (2000.0) a = 4.9317362 AU Inc. = 13.89646 n'= 0.08999209 q = 2.7691278 AU P = 10.952 years The following residuals in seconds of arc are from the above orbital elements: Date Code
