Nakano Note (Nakano wa Kangaeru noda) NK 4751 360P/WISE
The following improved orbital elements, by S. Nakano, are from 132 observations 2010 to 2017. 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. The comet will pass 0.073 AU from Jupiter on 2028 May 31 UT. See the previous orbits in NK 2016, NK 2725 and NK 3442 (= HICQ 2018). Epoch = 2017 Sept. 4.0 TT T = 2017 Aug. 18.42940 +/- 0.00053 (m.e.)
