Nakano Note (Nakano wa Kangaeru noda) NK 4663 P/2022 B1 (Wierzchos)
The following improved orbital elements, by S. Nakano, are from 75 observations 2021 Oct. 30 to 2022 Feb. 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.48 arc second. The comet will pass 0.38 AU from Jupiter on 2046 Feb. 8 UT. See an orbit in CBET 5094. Epoch = 2022 Mar. 2.0 TT T = 2022 Feb. 25.34911 +/- 0.00670 (m.e.)
