Nakano Note (Nakano wa Kangaeru noda) NK 3864 A/2018 V3
The following improved orbital elements, by S. Nakano, are from 81 observations 2018 Nov. 2 to 2019 Aug. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.27 arc second. The object will pass 0.37 AU from the Earth on 2019 Aug. 18.8 and 3.75 AU from Jupiter on 2019 Nov. 9 UT. See an orbit in HICQ 2018.
