Nakano Note (Nakano wa Kangaeru noda) NK 5024 317P/WISE
The following improved orbital elements, by S. Nakano, are from 92 observations 2005 to 2020. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.55 arc second. The comet has passed 0.71 AU from Jupiter on 2012 Nov. 29 UT. See the previous orbits in NK 2316, NK 2835 and NK 3421. Epoch = 2020 Sept.28.0 TT T = 2020 Sept.26.18634 +/- 0.00023 (m.e.)
