Nakano Note (Nakano wa Kangaeru noda) NK 5183 P/PANSTARRS (2014 A3 = 2023 X6)
The following improved orbital elements, by S. Nakano, are from 66 observations 2014 to 2024. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.40 arc second. Residuals from the prediction in NK 2902 were +10" for Right Ascension and -3" for Declination with the delta-T correction = -0.016 day. The comet has passed 0.0017 AU on 1971 May 21 and 0.62 AU on 2006 Sept. 10 from Jupiter. Also comet has passed 0.70 AU from Saturn on 1942 Dec. UT. A past orbit was T= 1954 02 11, q= 5.212, e= 0.247, Peri.= 205.9, Node= 68.4, i= 18.6, a= 6.920 AU, P= 18.2 years. See the previous orbits in HICQ 2014 and NK 2902.
