Nakano Note (Nakano wa Kangaeru noda) NK 3573 C/2016 E1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 139 observations 2016 Mar. 3 to 2018 Mar. 13. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. The comet has passed 0.62 AU from Saturn on 2014 Nov. 14 and 4.34 AU from Jupiter on 2017 Feb. 20 UT and also will pass 7.86 AU from Uranus on 2028 June 25. See the previous orbits in NK 3353 and NK 3509 (= HICQ 2018). Epoch = 2017 June 16.0 TT T = 2017 June 1.43618 +/- 0.00294 (m.e.)
